SETAUID(2) BSD System Calls Manual SETAUID(2)NAMEsetauid — set audit indentifier
The setauid() system call sets the active audit identifier for the cur‐
rent process from the au_id_t pointed to by auid. The value of AU_DEFAU‐
DITID (-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.
Upon successful completion, the value 0 is returned; otherwise the
value -1 is returned and the global variable errno is set to indicate the
The setauid() function will fail if:
[EFAULT] A failure occurred while data transferred to the ker‐
[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.
