+.Fc
+.Sh DESCRIPTION
+The
+.Nm libefi
+library provides access to a select set of the runtime services of the
+Extensible Firmware Interface (EFI).
+.Pp
+The
+.Fn efi_nextvarname
+function is used to enumerate the variables.
+The
+.Fa namesize
+parameter needs to be set to the size of the buffer pointed to by
+.Fa name .
+On return,
+.Fa namesize
+is set to the length of the variable name (including the terminating
+.Ql \e0 )
+irrespective of whether the buffer was big enough.
+The buffer pointed to by
+.Fa name
+contains the full or partial variable name on return.
+Only on successful completion of the request is the
+.Fa vendor
+updated.
+The values returned should be passed to successive calls to
+.Fn efi_nextvarname
+until all variables have been enumerated.
+.Pp
+The variable name and vendor as returned by
+.Fn efi_nextvarname
+can be passed to
+.Fn efi_getvar
+to obtain the value and attribute of the variable.
+The buffer that is to contain the value is specified by
+.Fa data
+and the size of the buffer is given by
+.Fa datasize .
+The attribute pointed to by
+.Fa attrib
+consists of the bit values defined by the EFI specification.
+.Pp
+Variables can be created, modified and deleted using the
+.Fn efi_setvar
+function.
+All new variables must be non-volatile and runtime accessible in
+order for the request to succeed.
+Note that for runtime accessable variables the boottime accessable bit must
+be set as well.
+To delete a variable, set
+.Fa datasize
+to 0.
+.Pp
+The vendor UUID is used to avoid collisions between variable names of
+different vendors.
+Variables created for use by
+.Fx
+should use the
+.Dv EFI_FREEBSD_VARIABLE
+UUID as defined in the
+.In libefi.h
+header file.
+.Sh RETURN VALUES
+Upon successful completion, these functions return 0.
+Otherwise, the error number is returned.
+These functions will fail if:
+.Bl -tag -width Er
+.It Bq Er EACCES
+Insufficient permissions to access the EFI services.
+.It Bq Er EILSEQ
+The variable name is not in UTF-8.
+.It Bq Er EINVAL
+The request has invalid parameters.
+.It Bq Er ENOENT
+The variable does not exist or no more variables exist.
+.It Bq Er ENOMEM
+Temporary storage could not be allocated.
+.It Bq Er EOVERFLOW
+The variable name is too long or the data is too big to fit in
+the buffer provided.
+.El
+.Sh SEE ALSO
+.Xr errno 2 ,
+.Xr uuid 3
+.Sh HISTORY
+The
+.Nm libefi
+library first appeared in
+.Fx 9.0
+for the ia64 architecture.
+.Sh AUTHORS
+The
+.Nm libefi
+library and this manual page were written by
+.An Marcel Moolenaar Aq marcel at FreeBSD.org .
