DESCRIPTION

20       The  getauid()  function  returns  the  audit  user  ID for the current
21       process. This value is initially set at login time and inherited by all
22       child  processes.  This  value  does not change when the real/effective
23       user IDs change, so it can be used to identify the logged-in user  even
24       when  running  a  setuid program. The audit user ID governs audit deci‐
25       sions for a process.
26
27
28       The setauid() function sets the audit user ID for the current process.
29

RETURN VALUES

31       Upon successful completion, the getauid() function  returns  the  audit
32       user ID of the current process on success. Otherwise, it returns −1 and
33       sets errno to indicate the error.
34
35
36       Upon successful completion the setauid() function returns 0. Otherwise,
37       −1 is returned and errno is set to indicate the error.
38
