getauid(2)							    getauid(2)

NAME
       getauid,	setauid	- get or set user audit	identity

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

       int getauid(au_id_t *auid);

       int setauid(au_id_t *auid);

       The  getauid()  function	 returns  the  audit  user  ID for the current
       process.	This value is initially	set at login time and inherited	by all
       child  processes.  This	value  does not	change when the	real/effective
       user IDs	change,	so it can be used to identify the logged-in user  even
       when  running  a	 setuid	program. The audit user	ID governs audit deci-
       sions for a process.

       The setauid() function sets the audit user ID for the current process.

       Upon successful completion, the getauid() function  returns  the	 audit
       user ID of the current process on success. Otherwise, it	returns	-1 and
       sets errno to indicate the error.

       Upon successful completion the setauid()	function returns 0. Otherwise,
       -1 is returned and errno	is set to indicate the error.

       The getauid() and setauid() functions will fail if:

       EFAULT	       The auid	argument points	to an invalid address.

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

       The getauid() function will fail	if:

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

USAGE
       Only  a	process	 with  appropriate privileges can successfully execute
       these calls.

       bsmconv(1M), audit(2), getaudit(2), privileges(5)

       The functionality described on this manual page is  available  only  if
       the  Basic Security Module (BSM)	has been enabled.  See bsmconv(1M) for
       more information.

       These functions have been superseded by getaudit(2) and setaudit().
