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 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.
