SETAUID(2) BSD System Calls Manual SETAUID(2)
NAME
setauid -- set audit indentifier
SYNOPSIS
#include <bsm/audit.h>
int
setauid(au_id_t *auid);
DESCRIPTION
The setauid() system call sets the active audit identifier for the current process from the au_id_t
pointed to by auid. The value of AU_DEFAUDITID (-1) should not be used for auid.
This system call requires an appropriate privilege to complete.
Once the audit identifier is set to some other value than AU_DEAUDITID (-1) then it is immutable. This
system call may be used to set the audit identifier after initially setting up the audit session with
the setaudit(2), or setaudit_addr(2) system call.
RETURN VALUES
Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global
variable errno is set to indicate the error.
ERRORS
The setauid() function will fail if:
[EFAULT] A failure occurred while data transferred to the kernel failed.
[EINVAL] An invalid value for auid was used. auid can be any value of type au_id_t except
AU_DEFAUDITID.
[EPERM] The process does not have sufficient permission to complete the operation.
