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);

       The  audit() function is used to write a record to the system audit log. The data pointed to by	record is written to the log after a mini-
       mal  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.

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

       The audit() function will fail if:

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

       EINVAL	       The  record  header  token ID is invalid or the length is  either less than the header token size or greater than MAXAUDIT-
		       DATA.

       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.
