au_open(3BSM)	    Security and Auditing Library Functions	 au_open(3BSM)

NAME
       au_open, au_close, au_write - construct and write audit records

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

       int au_close(int d, int keep, short event);

       int au_open(void);

       int au_write(int d, token_t *m);

DESCRIPTION
       The  au_open()  function	 returns  an  audit record descriptor to which
       audit tokens can be written using au_write(). The audit record descrip‐
       tor  is	an  integer  value  that identifies a storage area where audit
       records are accumulated.

       The au_close() function terminates the life of an audit	record	 d  of
       type   event   started	by   au_open().	  If  the  keep	 parameter  is
       AU_TO_NO_WRITE, the data contained therein is discarded.	 If  the  keep
       parameter  is AU_TO_WRITE, the additional parameters are used to create
       a header token.	Depending on the audit policy information  obtained by
       auditon(2),  additional tokens such as  sequence and trailer tokens can
       be added to the record. The au_close() function then writes the	record
       to  the	audit  trail by calling audit(2).  Any memory used is freed by
       calling free(3C).

       The au_write() function adds the audit token pointed to	by  m  to  the
       audit  record  identified  by the descriptor d. After this call is made
       the audit token is no longer available to the caller.

RETURN VALUES
       Upon successful completion, au_open() returns an audit record  descrip‐
       tor.  If	 a descriptor could not be allocated, au_open() returns −1 and
       sets errno to indicate the error.

       Upon successful completion, au_close()  returns 0. If d is  an  invalid
       or  corrupted  descriptor  or  if  audit() fails, au_close() returns −1
       without setting errno. If audit() fails, errno is set  to  one  of  the
       error values described on the audit(2) manual page.

       Upon  successful	 completion, au_write()	 returns 0. If d is an invalid
       descriptor or m is an invalid token, or if  audit()  fails,  au_write()
       returns −1 without setting errno. If audit() fails, errno is set to one
       of the error values described on the audit(2) manual page.

ERRORS
       The au_open() function will fail if:

       ENOMEM	 The physical limits of the system  have  been	exceeded  such
		 that sufficient memory cannot be allocated.

       EAGAIN	 There	is currently insufficient memory available. The appli‐
		 cation can try again later.
