getauid(2)				   System Calls 			       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);

DESCRIPTION
       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 decisions  for
       a process.

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

RETURN VALUES
       Upon  successful  completion, the getauid() function returns the audit user ID of the cur-
       rent 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.

ERRORS
       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 call-
		 ing process.

       The getauid() function will fail if:

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

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

NOTES
       The  functionality described on this manual page is available only if the Solaris Auditing
       has been enabled.  See bsmconv(1M) for more information.

       These functions have been superseded by getaudit(2) and setaudit().
