 AUDIT 2 "Mar 6, 2017"
 NAME
audit - write a record to the audit log
 SYNOPSIS

cc [ flag ... ] file ... -lbsm  -lsocket   -lnsl  [ library... ]
#include <sys/param.h>
#include <bsm/libbsm.h>

int audit(caddr_t record, int length);


 DESCRIPTION

The audit() function queues a record for writing to the system audit log.
The data pointed to by record is queued for the log after a minimal
consistency check, with the length parameter specifying the size of the
record in bytes. The data should be a well-formed audit record as described
by audit.log(4).

The kernel validates the record header token type and length, and sets the
time stamp value before writing the record to the audit log. The kernel does
not do any preselection for user-level generated events. If the audit policy is
set to include sequence or trailer tokens, the kernel will append them to the
record.
 RETURN VALUES

Upon successful completion, 0 is returned. Otherwise, -1 is
returned and errno is set to indicate the error.
 ERRORS

The audit() function will fail if:
E2BIG

The record length is greater than the maximum allowed record length.


EFAULT

The record argument points outside the process's allocated address space.


EINVAL

The header token in the record is invalid.


ENOTSUP

Audit is not defined for this system.


EPERM

The {PRIV_PROC_AUDIT} privilege is not asserted in the effective set of
the calling process.


 USAGE

Only privileged processes can successfully execute this call.
