SYNOPSIS

#include <bsm/audit.h>

int

audit(const char *record, u_int length);

DESCRIPTION

The audit() system call submits a completed BSM audit record to the system audit log.

The record argument is a pointer to the specific event to be recorded and length is the size in bytes of the data to be written.

RETURN VALUES

Upon successful completion, the value 0 is returned; otherwise the value −1 is returned and the global variable errno is set to indicate the error.

ERRORS

The audit() system call will fail and the data never written if:

[EFAULT]

The record argument is beyond the allocated address space of the process.

[EINVAL]

The token ID is invalid or length is larger than MAXAUDITDATA.

[EPERM]

The process does not have sufficient permission to complete the operation.

AUTHORS

This software was created by McAfee Research, the security research division of McAfee, Inc., under contract to Apple Computer Inc. Additional authors include Wayne Salamon, Robert Watson, and SPARTA Inc.

The Basic Security Module (BSM) interface to audit records and audit event stream format were defined by Sun Microsystems.

This manual page was written by Tom Rhodes 〈trhodes@FreeBSD.org〉.

BUGS

The FreeBSD kernel does not fully validate that the argument passed is syntactically valid BSM. Submitting invalid audit records may corrupt the audit log.
