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 descriptor. 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 application can try again later.
