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 decisions 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.

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       These functions have been superseded by getaudit(2) and setaudit().
