+.Sh SYNOPSIS
+.In aio.h
+.Ft int
+.Fn aio_fsync "int op" "struct aiocb *iocb"
+.Sh DESCRIPTION
+The
+.Fn aio_fsync
+system call allows the calling process to move all modified data
+associated with the descriptor
+.Fa iocb->aio_fildes
+to a permanent storage device.
+The call returns immediately after the synchronization request has been
+enqueued to the descriptor; the synchronization may or may not have
+completed at the time the call returns.
+.Pp
+The
+.Fa op
+argument can only be set to
+.Dv O_SYNC
+to cause all currently queued I/O operations to be completed
+as if by a call to
+.Xr fsync 2 .
+.Pp
+If _POSIX_PRIORITIZED_IO is defined, and the descriptor supports it,
+then the enqueued operation is submitted at a priority equal to that
+of the calling process minus
+.Fa iocb->aio_reqprio .
+.Pp
+The
+.Fa iocb
+pointer may be subsequently used as an argument to
+.Fn aio_return
+and
+.Fn aio_error
+in order to determine return or error status for the enqueued operation
+while it is in progress.
+.Pp
+If the request could not be enqueued (generally due to invalid arguments),
+the call returns without having enqueued the request.
+.Pp
+The
+.Fa iocb->aio_sigevent
+structure can be used to request notification of the operation's
+completion as described in
+.Xr aio 4 .
+.Sh RESTRICTIONS
+The Asynchronous I/O Control Block structure pointed to by
+.Fa iocb
+must remain valid until the
+operation has completed.
+.Pp
+The asynchronous I/O control buffer
+.Fa iocb
+should be zeroed before the
+.Fn aio_fsync
+call to avoid passing bogus context information to the kernel.
+.Pp
+Modification of the Asynchronous I/O Control Block structure is not allowed
+while the request is queued.
+.Sh RETURN VALUES

+.Pp
+The following conditions may be synchronously detected when the
+.Fn aio_fsync
+system call is made, or asynchronously, at any time thereafter.
+If they are detected at call time,
+.Fn aio_fsync
+returns -1 and sets
+.Va errno
+appropriately; otherwise the
+.Fn aio_return
+system call must be called, and will return -1, and
+.Fn aio_error
+must be called to determine the actual value that would have been

+.Sh DESCRIPTION
+If a file descriptor is granted the
+.Dv CAP_IOCTL
+capability right, the list of allowed
+.Xr ioctl 2
+commands can be selectively reduced (but never expanded) with the
+.Fn cap_ioctls_limit
+system call.
+The
+.Fa cmds
+argument is an array of
+.Xr ioctl 2
+commands and the
+.Fa ncmds
+argument specifies the number of elements in the array.
+There can be up to
+.Va 256
+elements in the array.
+.Pp
+The list of allowed ioctl commands for a given file descriptor can be obtained
+with the
+.Fn cap_ioctls_get
+system call.
+The
+.Fa cmds
+argument points at memory that can hold up to
+.Fa maxcmds
+values.
+The function populates the provided buffer with up to
+.Fa maxcmds
+elements, but always returns the total number of ioctl commands allowed for the
+given file descriptor.
+The total number of ioctls commands for the given file descriptor can be
+obtained by passing
+.Dv NULL as the
+.Fa cmds
+argument and
+.Va 0
+as the
+.Fa maxcmds
+argument.
+If all ioctl commands are allowed
+.Dv ( CAP_IOCTL
+capability right is assigned to the file descriptor and the
+.Fn cap_ioctls_limit
+system call was never called for this file descriptor), the
+.Fn cap_ioctls_get
+system call will return
+.Dv CAP_IOCTLS_ALL
+and won't modify the buffer pointed to by the
+.Fa cmds
+argument.
+.Sh RETURN VALUES

+The

+In this case the file to be changed is determined relative to the directory

+.Fn ffclock_getestimate "struct ffclock_estimate *cest"
+.Ft int
+.Fn ffclock_setestimate "struct ffclock_estimate *cest"
+.Sh DESCRIPTION
+The ffclock is an alternative method to synchronise the system clock.
+The ffclock implements a feed-forward paradigm and decouples the timestamping
+and timekeeping kernel functions.
+This ensures that past clock errors do not affect current timekeeping, an
+approach radically different from the feedback alternative implemented by the
+ntpd daemon when adjusting the system clock.
+The feed-forward approach has demonstrated better performance and higher
+robustness than a feedback approach when synchronising over the network.
+.Pp
+In the feed-forward context, a
+.Em timestamp
+is a cumulative value of the ticks of the timecounter, which can be converted
+into seconds by using the feed-forward
+.Em clock estimates .
+.Pp
+The
+.Fn ffclock_getcounter
+system call allows the calling process to retrieve the current value of the
+feed-forward counter maintained by the kernel.
+.Pp
+The
+.Fn ffclock_getestimate
+and
+.Fn ffclock_setestimate
+system calls allow the caller to get and set the kernel's feed-forward clock
+parameter estimates respectively.
+The
+.Fn ffclock_setestimate
+system call should be invoked by a single instance of a feed-forward
+synchronisation daemon.
+The
+.Fn ffclock_getestimate
+system call can be called by any process to retrieve the feed-forward clock
+estimates.
+.Pp
+The feed-forward approach does not require that the clock estimates be retrieved
+every time a timestamp is to be converted into seconds.
+The number of system calls can therefore be greatly reduced if the calling
+process retrieves the clock estimates from the clock synchronisation daemon
+instead.
+The
+.Fn ffclock_getestimate
+must be used when the feed-forward synchronisation daemon is not running
+.Po see
+.Sx USAGE
+below
+.Pc .
+.Pp
+The clock parameter estimates structure pointed to by
+.Fa cest
+is defined in
+.In sys/timeffc.h
+as:
+.Bd -literal
+struct ffclock_estimate {
+ struct bintime update_time; /* Time of last estimates update. */
+ ffcounter update_ffcount; /* Counter value at last update. */
+ ffcounter leapsec_next; /* Counter value of next leap second. */
+ uint64_t period; /* Estimate of counter period. */
+ uint32_t errb_abs; /* Bound on absolute clock error [ns]. */
+ uint32_t errb_rate; /* Bound on counter rate error [ps/s]. */
+ uint32_t status; /* Clock status. */
+ int16_t leapsec_total; /* All leap seconds seen so far. */
+ int8_t leapsec; /* Next leap second (in {-1,0,1}). */
+};
+.Ed
+.Pp
+Only the super-user may set the feed-forward clock estimates.
+.Sh RETURN VALUES
+.Rv -std
+.Sh ERRORS
+The following error codes may be set in
+.Va errno :
+.Bl -tag -width Er
+.It Bq Er EFAULT
+The
+.Fa ffcount
+or
+.Fa cest
+pointer referenced invalid memory.
+.It Bq Er EPERM
+A user other than the super-user attempted to set the feed-forward clock
+parameter estimates.
+.El
+.Sh USAGE
+The feed-forward paradigm enables the definition of specialised clock functions.
+.Pp
+In its simplest form,
+.Fn ffclock_getcounter
+can be used to establish strict order between events or to measure small time
+intervals very accurately with a minimum performance cost.
+.Pp
+Different methods exist to access absolute time
+.Po or
+.Qq wall-clock time
+.Pc tracked by the ffclock.
+The simplest method uses the ffclock sysctl interface
+.Va kern.ffclock
+to make the system clock return the ffclock time.
+The
+.Xr clock_gettime 2
+system call can then be used to retrieve the current time seen by the
+feed-forward clock.
+Note that this setting affects the entire system and that a feed-forward
+synchronisation daemon should be running.
+.Pp
+A less automated method consists of retrieving the feed-forward counter
+timestamp from the kernel and using the feed-forward clock parameter estimates
+to convert the timestamp into seconds.
+The feed-forward clock parameter estimates can be retrieved from the kernel or
+from the synchronisation daemon directly (preferred).
+This method allows converting timestamps using different clock models as needed
+by the application, while collecting meaningful upper bounds on current clock
+error.

.Sh NOTES
Although this implementation does not impose any alignment restrictions on
the
.Fa offset
argument, a portable program must only use page-aligned values.
+.Pp
+Large page mappings require that the pages backing an object be
+aligned in matching blocks in both the virtual address space and RAM.
+The system will automatically attempt to use large page mappings when
+mapping an object that is already backed by large pages in RAM by
+aligning the mapping request in the virtual address space to match the
+alignment of the large physical pages.
+The system may also use large page mappings when mapping portions of an
+object that are not yet backed by pages in RAM.
+The
+.Dv MAP_ALIGNED_SUPER
+flag is an optimization that will align the mapping request to the
+size of a large page similar to
+.Dv MAP_ALIGNED ,
+except that the system will override this alignment if an object already
+uses large pages so that the mapping will be consistent with the existing
+large pages.
+This flag is mostly useful for maximizing the use of large pages on the
+first mapping of objects that do not yet have pages present in RAM.

+.Sh LIBRARY
+.Lb libc
+.Sh SYNOPSIS
+.In sys/procctl.h
+.Ft int
+.Fn procctl "idtype_t idtype" "id_t id" "int cmd" "void *arg"
+.Sh DESCRIPTION
+The
+.Fn procctl
+system call provides for control over processes.
+The
+.Fa idtype
+and
+.Fa id
+arguments specify the set of processes to control.
+If multiple processes match the identifier,
+.Nm
+will make a
+.Dq best effort
+to control as many of the selected processes as possible.
+An error is only returned if no selected processes successfully complete
+the request.
+The following identifier types are supported:
+.Bl -tag -width "Dv P_PGID"
+.It Dv P_PID
+Control the process with the process ID
+.Fa id .
+.It Dv P_PGID
+Control processes belonging to the process group with the ID
+.Fa id .
+.El
+.Pp
+The control request to perform is specified by the
+.Fa cmd
+argument.
+The following commands are supported:
+.Bl -tag -width "Dv PROC_REAP_GETPIDS"
+.It Dv PROC_SPROTECT
+Set process protection state.
+This is used to mark a process as protected from being killed if the system
+exhausts available memory and swap.
+The
+.Fa arg
+parameter must point to an integer containing an operation and zero or more
+optional flags.
+The following operations are supported:
+.Bl -tag -width "Dv PPROT_CLEAR"
+.It Dv PPROT_SET
+Mark the selected processes as protected.
+.It Dv PPROT_CLEAR
+Clear the protected state of selected processes.
+.El
+.Pp
+The following optional flags are supported:
+.Bl -tag -width "Dv PPROT_DESCE"
+.It Dv PPROT_DESCEND
+Apply the requested operation to all child processes of each selected process
+in addition to each selected process.
+.It Dv PPROT_INHERIT
+When used with
+.Dv PPROT_SET ,
+mark all future child processes of each selected process as protected.
+Future child processes will also mark all of their future child processes.
+.El
+.It Dv PROC_REAP_ACQUIRE
+Acquires the reaper status for the current process.
+The status means that children orphaned by the reaper's descendants
+that were forked after the acquisition of the status are reparented to the
+reaper.
+After the system initialization,
+.Xr init 8
+is the default reaper.
+.Pp
+.It Dv PROC_REAP_RELEASE
+Releases the reaper state for the current process.
+The reaper of the current process becomes the new reaper of the
+current process's descendants.
+.It Dv PROC_REAP_STATUS
+Provides the information about the reaper of the specified process,
+or the process itself when it is a reaper.
+The
+.Fa data
+argument must point to a
+.Vt procctl_reaper_status
+structure which is filled in by the syscall on successful return.
+.Bd -literal
+struct procctl_reaper_status {
+ u_int rs_flags;
+ u_int rs_children;
+ u_int rs_descendants;
+ pid_t rs_reaper;
+ pid_t rs_pid;
+};
+.Ed
+The
+.Fa rs_flags
+may have the following flags returned:
+.Bl -tag -width "Dv REAPER_STATUS_REALINIT"
+.It Dv REAPER_STATUS_OWNED
+The specified process has acquired the reaper status and has not
+released it.
+When the flag is returned, the specified process
+.Fa id ,
+pid, identifies the reaper, otherwise the
+.Fa rs_reaper
+field of the structure is set to the pid of the reaper
+for the specified process id.
+.It Dv REAPER_STATUS_REALINIT
+The specified process is the root of the reaper tree, i.e.
+.Xr init 8 .
+.El
+The
+.Fa rs_children
+field returns the number of children of the reaper among the descendands.
+It is possible to have a child which reaper is not the specified process,
+since the reaper for the existing children is not reset on the
+.Dv PROC_REAP_ACQUIRE
+operation.
+The
+.Fa rs_descendants
+field returns the total number of descendants of the reaper(s),
+not counting descendants of the reaper in the subtree.
+The
+.Fa rs_reaper
+field returns the reaper pid.
+The
+.Fa rs_pid
+returns the pid of one reaper child if there are any descendants.
+.It Dv PROC_REAP_GETPIDS
+Queries the list of descendants of the reaper of the specified process.
+The request takes a pointer to a
+.Vt procctl_reaper_pids
+structure in the
+.Fa data
+parameter.
+.Bd -literal
+struct procctl_reaper_pids {
+ u_int rp_count;
+ struct procctl_reaper_pidinfo *rp_pids;
+};
+.Ed
+When called, the
+.Fa rp_pids
+field must point to an array of
+.Vt procctl_reaper_pidinfo
+structures, to be filled in on return,
+and the
+.Fa rp_count
+field must specify the size of the array,
+into which no more than
+.Fa rp_count
+elements will be filled in by the kernel.
+.Pp
+The
+.Vt "struct procctl_reaper_pidinfo"
+structure provides some information about one of the reaper's descendants.
+Note that for a descendant that is not a child, it may be incorrectly
+identified because of a race in which the original child process exited
+and the exited process's pid was reused for an unrelated process.
+.Bd -literal
+struct procctl_reaper_pidinfo {
+ pid_t pi_pid;
+ pid_t pi_subtree;
+ u_int pi_flags;
+};
+.Ed
+The
+.Fa pi_pid
+field is the process id of the descendant.
+The
+.Fa pi_subtree
+field provides the pid of the child of the reaper, which is the (grand-)parent
+of the process.
+The
+.Fa pi_flags
+field returns the following flags, further describing the descendant:
+.Bl -tag -width "Dv REAPER_PIDINFO_REAPER"
+.It Dv REAPER_PIDINFO_VALID
+Set to indicate that the
+.Vt procctl_reaper_pidinfo
+structure was filled in by the kernel.
+Zero-filling the
+.Fa rp_pids
+array and testing the
+.Dv REAPER_PIDINFO_VALID
+flag allows the caller to detect the end
+of the returned array.
+.It Dv REAPER_PIDINFO_CHILD
+The
+.Fa pi_pid
+field identifies the direct child of the reaper.
+.It Dv REAPER_PIDINFO_REAPER
+The reported process is itself a reaper.
+The descendants of the subordinate reaper are not reported.
+.El
+.It Dv PROC_REAP_KILL
+Request to deliver a signal to some subset of the descendants of the reaper.
+The
+.Fa data
+parameter must point to a
+.Vt procctl_reaper_kill
+structure, which is used both for parameters and status return.
+.Bd -literal
+struct procctl_reaper_kill {
+ int rk_sig;
+ u_int rk_flags;
+ pid_t rk_subtree;
+ u_int rk_killed;
+ pid_t rk_fpid;
+};
+.Ed
+The
+.Fa rk_sig
+field specifies the signal to be delivered.
+Zero is not a valid signal number, unlike
+.Xr kill 2 .
+The
+.Fa rk_flags
+field further directs the operation.
+It is or-ed from the following flags:
+.Bl -tag -width "Dv REAPER_KILL_CHILDREN"
+.It Dv REAPER_KILL_CHILDREN
+Deliver the specified signal only to direct children of the reaper.
+.It Dv REAPER_KILL_SUBTREE
+Deliver the specified signal only to descendants that were forked by
+the direct child with pid specified in the
+.Fa rk_subtree
+field.
+.El
+If neither the
+.Dv REAPER_KILL_CHILDREN
+nor the
+.Dv REAPER_KILL_SUBTREE
+flags are specified, all current descendants of the reaper are signalled.
+.Pp
+If a signal was delivered to any process, the return value from the request
+is zero.
+In this case, the
+.Fa rk_killed
+field identifies the number of processes signalled.
+The
+.Fa rk_fpid
+field is set to the pid of the first process for which signal
+delivery failed, e.g. due to the permission problems.
+If no such process exist, the
+.Fa rk_fpid
+field is set to -1.
+.It Dv PROC_TRACE_CTL
+Enable or disable tracing of the specified process(es), according to the
+value of the integer argument.
+Tracing includes attachment to the process using
+.Xr ptrace 2
+and
+.Xr ktrace 2 ,
+debugging sysctls,
+.Xr hwpmc 4 ,
+.Xr dtrace 1
+and core dumping.
+Possible values for the
+.Fa data
+argument are:
+.Bl -tag -width "Dv PROC_TRACE_CTL_DISABLE_EXEC"
+.It Dv PROC_TRACE_CTL_ENABLE
+Enable tracing, after it was disabled by
+.Dv PROC_TRACE_CTL_DISABLE .
+Only allowed for self.
+.It Dv PROC_TRACE_CTL_DISABLE
+Disable tracing for the specified process.
+Tracing is re-enabled when the process changes the executing
+program with
+.Xr execve 2
+syscall.
+A child inherits the trace settings from the parent on
+.Xr fork 2 .
+.It Dv PROC_TRACE_CTL_DISABLE_EXEC
+Same as
+.Dv PROC_TRACE_CTL_DISABLE ,
+but the setting persist for the process even after
+.Xr execve 2 .
+.El
+.It Dv PROC_TRACE_STATUS
+Returns the current tracing status for the specified process in
+the integer variable pointed to by
+.Fa data .
+If tracing is disabled,
+.Fa data
+is set to -1.
+If tracing is enabled, but no debugger is attached by
+.Xr ptrace 2
+syscall,
+.Fa data
+is set to 0.
+If a debugger is attached,
+.Fa data
+is set to the pid of the debugger process.
+.El
+.Sh NOTES
+Disabling tracing on a process should not be considered a security
+feature, as it is bypassable both by the kernel and privileged processes,
+and via other system mechanisms.
+As such, it should not be relied on to reliably protect cryptographic
+keying material or other confidential data.
+.Sh RETURN VALUES
+If an error occurs, a value of -1 is returned and
+.Va errno
+is set to indicate the error.
+.Sh ERRORS

.Pp
+A traced process may report additional signal stops corresponding to
+events in the traced process.
+These additional signal stops are reported as
+.Dv SIGTRAP
+or
+.Dv SIGSTOP
+signals.
+The tracing process can use the
+.Dv PT_LWPINFO
+request to determine which events are associated with a
+.Dv SIGTRAP
+or
+.Dv SIGSTOP
+signal.
+Note that multiple events may be associated with a single signal.
+For example, events indicated by the
+.Dv PL_FLAG_BORN ,
+.Dv PL_FLAG_FORKED ,
+and
+.Dv PL_FLAG_EXEC
+flags are also reported as a system call exit event
+.Pq Dv PL_FLAG_SCX .
+The signal stop for a new child process enabled via
+.Dv PTRACE_FORK
+will report a
+.Dv SIGSTOP
+signal.
+All other additional signal stops use
+.Dv SIGTRAP .
+.Pp
+Each traced process has a tracing event mask.
+An event in the traced process only reports a
+signal stop if the corresponding flag is set in the tracing event mask.
+The current set of tracing event flags include:
+.Bl -tag -width "Dv PTRACE_SYSCALL"
+.It Dv PTRACE_EXEC
+Report a stop for a successful invocation of
+.Xr execve 2 .
+This event is indicated by the
+.Dv PL_FLAG_EXEC

+.Vt "struct ptrace_lwpinfo" .
+.It Dv PTRACE_SCE

+This event is indicated by the
+.Dv PL_FLAG_SCE
+flag in the
+.Va pl_flags
+member of
+.Vt "struct ptrace_lwpinfo" .
+.It Dv PTRACE_SCX
+Report a stop on each system call exit.
+This event is indicated by the
+.Dv PL_FLAG_SCX
+flag in the
+.Va pl_flags
+member of
+.Vt "struct ptrace_lwpinfo" .
+.It Dv PTRACE_SYSCALL
+Report stops for both system call entry and exit.
+.It Dv PTRACE_FORK
+This event flag controls tracing for new child processes of a traced process.
+.Pp
+When this event flag is enabled,
+new child processes will enable tracing and stop before executing their
+first instruction.
+The new child process will include the
+.Dv PL_FLAG_CHILD
+flag in the
+.Va pl_flags
+member of
+.Vt "struct ptrace_lwpinfo" .
+The traced process will report a stop that includes the
+.Dv PL_FLAG_FORKED
+flag.
+The process ID of the new child process will also be present in the
+.Va pl_child_pid
+member of
+.Vt "struct ptrace_lwpinfo" .
+If the new child process was created via
+.Xr vfork 2 ,
+the traced process's stop will also include the
+.Dv PL_FLAG_VFORKED
+flag.
+Note that new child processes will be attached with the default
+tracing event mask;
+they do not inherit the event mask of the traced process.
+.Pp
+When this event flag is not enabled,
+new child processes will execute without tracing enabled.
+.It Dv PTRACE_LWP
+This event flag controls tracing of LWP
+.Pq kernel thread
+creation and destruction.
+When this event is enabled,
+new LWPs will stop and report an event with
+.Dv PL_FLAG_BORN
+set before executing their first instruction,
+and exiting LWPs will stop and report an event with
+.Dv PL_FLAG_EXITED
+set before completing their termination.
+.Pp
+Note that new processes do not report an event for the creation of their
+initial thread,
+and exiting processes do not report an event for the termination of the
+last thread.
+.It Dv PTRACE_VFORK
+Report a stop event when a parent process resumes after a
+.Xr vfork 2 .
+.Pp
+When a thread in the traced process creates a new child process via
+.Xr vfork 2 ,
+the stop that reports
+.Dv PL_FLAG_FORKED
+and
+.Dv PL_FLAG_SCX
+occurs just after the child process is created,
+but before the thread waits for the child process to stop sharing process
+memory.
+If a debugger is not tracing the new child process,
+it must ensure that no breakpoints are enabled in the shared process
+memory before detaching from the new child process.
+This means that no breakpoints are enabled in the parent process either.
+.Pp
The
+.Dv PTRACE_VFORK
+flag enables a new stop that indicates when the new child process stops
+sharing the process memory of the parent process.
+A debugger can reinsert breakpoints in the parent process and resume it
+in response to this event.
+This event is indicated by setting the

+.Sh DESCRIPTION
+These system calls are used to manipulate and query the resource limits
+database.
+For all functions,
+.Fa inbuflen
+refers to the length of the buffer pointed to by
+.Fa inbufp
+and
+.Fa outbuflen
+refers to the length of the buffer pointed to by
+.Fa outbufp .
+.Pp
+The
+.Fn rctl_add_rule
+function adds the rule pointed to by
+.Fa inbufp
+to the resource limits database.
+The
+.Fa outbufp
+and
+.Fa outbuflen
+arguments are unused.
+Rule format is as described in
+.Xr rctl 8 ,
+with exceptions noted in the
+.Sx RULES AND FILTERS
+section.
+.Pp
+The
+.Fn rctl_get_limits
+function returns in
+.Fa outbufp
+a comma-separated list of rules that apply to the process that
+matches the filter specified in
+.Fa inbufp .
+This includes rules with a subject of the process itself as well as rules
+with a different subject (such as user or loginclass) that apply to the
+process.
+.Pp
+The
+.Fn rctl_get_racct
+function returns resource usage information for a given subject.
+The subject is specified by passing a filter in
+.Fa inbufp .
+Filter syntax is as described in
+.Xr rctl 8 ,
+with exceptions noted in the
+.Sx RULES AND FILTERS
+section.
+A comma-separated list of resources and the amount used of each by the
+specified subject is returned in
+.Fa outbufp .
+The resource and amount is formatted as
+.Qq resource=amount .
+.Pp
+The
+.Fn rctl_get_rules
+function returns in
+.Fa outbufp
+a comma-separated list of rules from the resource limits database that
+match the filter passed in
+.Fa inbufp .
+Filter syntax is as described in
+.Xr rctl 8 ,
+with exceptions noted in the
+.Sx RULES AND FILTERS
+section.
+A filter of
+.Va ::
+may be passed to return all rules.
+.Pp
+The
+.Fn rctl_remove_rule
+function removes all rules matching the filter passed in
+.Fa inbufp
+from the resource limits database.
+Filter syntax is as described in
+.Xr rctl 8 ,
+with exceptions noted in the
+.Sx RULES AND FILTERS
+section.
+.Fa outbufp
+and
+.Fa outbuflen
+are unused.
+.Sh RULES AND FILTERS
+This section explains how the rule and filter format described in
+.Xr rctl 8
+differs from the format passed to the system calls themselves.
+The rctl tool provides several conveniences that the system calls do not.
+When using the system call:
+.Bl -dash -offset indent
+.It
+The subject must be fully specified.
+For example, abbreviating
+.Ql user
+to
+.Ql u
+is not acceptable.
+.It
+User and group IDs must be numeric.
+For example,
+.Ql root
+must be expressed as
+.Ql 0 .
+.It
+Units are not permitted on resource amounts.
+For example, a quantity of 1024 bytes must be expressed as
+.Ql 1024
+and not
+.Ql 1k .
+.El
+.Sh RETURN VALUES
+.Rv -std
+.Sh ERRORS
+The rctl system calls may fail if:
+.Bl -tag -width Er
+.It Bq Er ENOSYS
+RACCT/RCTL support is not present in the kernel or the
+.Va kern.racct.enable
+sysctl is 0.
+.It Bq Er EINVAL
+The rule or filter passed in
+.Fa inbufp
+is invalid.
+.It Bq Er EPERM
+User has insufficient privileges to carry out the requested operation.
+.It Bq Er E2BIG
+.Fa inbufp
+or
+.Fa outbufp
+are too large.
+.It Bq Er ESRCH
+No process matched the provided rule or filter.
+.It Bq Er ENAMETOOLONG
+The loginclass or jail name specified is too long.
+.It Bq Er ERANGE
+The rule amount is outside of the allowable range or
+.Fa outbufp
+is too small.
+.It Bq Er EOPNOTSUPP
+The requested operation is not supported for the given rule or filter.
+.It Bq Er EFAULT
+.Fa inbufp
+or

+.Bf -symbolic
+This function is intended for implementing threading.
+Normal applications should use
+.Xr pthread_cond_timedwait 3
+together with
+.Xr pthread_cond_broadcast 3
+for typical safe suspension with cooperation of the thread

+.Ef
+.Pp
+The
+.Fn thr_suspend
+system call puts the calling thread in a suspended state, where it is
+not eligible for CPU time.
+This state is exited by another thread calling
+.Xr thr_wake 2 ,
+when the time interval specified by
+.Fa timeout
+has elapsed,
+or by the delivery of a signal to the suspended thread.
+.Pp
+If the
+.Fa timeout
+argument is
+.Dv NULL ,
+the suspended state can be only terminated by explicit
+.Fn thr_wake
+or signal.
+.Pp
+If a wake from
+.Xr thr_wake 2
+was delivered before the
+.Nm
+call, the thread is not put into a suspended state.
+Instead, the call
+returns immediately without an error.
+.Pp
+If a thread previously called
+.Xr thr_wake 2
+with its own thread identifier, which resulted in setting the internal kernel
+flag to immediately abort interruptible sleeps with an
+.Er EINTR
+error
+.Po
+see
+.Xr thr_wake 2
+.Pc ,
+the flag is cleared.
+As with
+.Xr thr_wake 2
+called from another thread, the next
+.Nm
+call does not result in suspension.

+.Sh RETURN VALUES

+.Sh LIBRARY
+.Lb libc
+.Sh SYNOPSIS
+.In sys/stat.h
+.Ft int
+.Fn futimens "int fd" "const struct timespec times[2]"
+.Ft int
+.Fo utimensat
+.Fa "int fd"
+.Fa "const char *path"
+.Fa "const struct timespec times[2]"
+.Fa "int flag"
+.Fc
+.Sh DESCRIPTION
+The access and modification times of the file named by
+.Fa path
+or referenced by
+.Fa fd
+are changed as specified by the argument
+.Fa times .
+The inode-change-time of the file is set to the current time.
+.Pp
+If
+.Fa path
+specifies a relative path,
+it is relative to the current working directory if
+.Fa fd
+is
+.Dv AT_FDCWD
+and otherwise relative to the directory associated with the file descriptor
+.Fa fd .
+.Pp
+The
+.Va tv_nsec
+field of a
+.Vt timespec
+structure
+can be set to the special value
+.Dv UTIME_NOW
+to set the current time, or to
+.Dv UTIME_OMIT
+to leave the time unchanged.
+In either case, the
+.Va tv_sec
+field is ignored.
+.Pp
+If
+.Fa times
+is
+.No non- Ns Dv NULL ,
+it is assumed to point to an array of two timespec structures.
+The access time is set to the value of the first element, and the
+modification time is set to the value of the second element.
+For file systems that support file birth (creation) times (such as
+.Dv UFS2 ) ,
+the birth time will be set to the value of the second element
+if the second element is older than the currently set birth time.
+To set both a birth time and a modification time,
+two calls are required; the first to set the birth time
+and the second to set the (presumably newer) modification time.
+Ideally a new system call will be added that allows the setting
+of all three times at once.
+If
+.Fa times
+is
+.Dv NULL ,
+this is equivalent to passing
+a pointer to an array of two timespec structures
+with both
+.Va tv_nsec
+fields set to
+.Dv UTIME_NOW .
+.Pp
+If both
+.Va tv_nsec
+fields are
+.Dv UTIME_OMIT ,
+the timestamps remain unchanged and
+no permissions are needed for the file itself,
+although search permissions may be required for the path prefix.
+The call may or may not succeed if the named file does not exist.
+.Pp
+If both
+.Va tv_nsec
+fields are
+.Dv UTIME_NOW ,
+the caller must be the owner of the file, have permission to
+write the file, or be the super-user.
+.Pp
+For all other values of the timestamps,
+the caller must be the owner of the file or be the super-user.
+.Pp
+The values for the
+.Fa flag
+argument of the
+.Fn utimensat
+system call
+are constructed by a bitwise-inclusive OR of flags from the following list,
+defined in
+.In fcntl.h :
+.Bl -tag -width indent
+.It Dv AT_SYMLINK_NOFOLLOW
+If
+.Fa path
+names a symbolic link, the symbolic link's times are changed.
+By default,
+.Fn utimensat
+changes the times of the file referenced by the symbolic link.
+.El
+.Sh RETURN VALUES
+.Rv -std
+.Sh COMPATIBILITY
+If the running kernel does not support this system call,
+a wrapper emulates it using
+.Xr fstatat 2 ,
+.Xr futimesat 2
+and
+.Xr lutimes 2 .
+As a result, timestamps will be rounded down to the nearest microsecond,
+.Dv UTIME_OMIT
+is not atomic and
+.Dv AT_SYMLINK_NOFOLLOW
+is not available with a path relative to a file descriptor.
