getauid(2)                       System Calls                       getauid(2)



NAME
       getauid, setauid - get and set user audit identity

SYNOPSIS
       cc [ flag ... ] file ... -lbsm -lsocket -lnsl -lintl [ 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 deci-
       sions 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 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.

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 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.

NOTES

       the  Basic Security Module (BSM) has been enabled.  See bsmconv(1M) for
       more information.

       These system calls have been superseded by getaudit(2) and setaudit().
