audit_set_loginuid_immutable − make loginuid value immutable
#include <libaudit.h>
int audit_set_loginuid_immutable(int fd);"
audit_set_loginuid_immutable() locks the loginuid so that it can no longer be changed. The descriptor fd must be an open audit netlink socket. This call is equivalent to using audit_set_feature() to enable and lock the AUDIT_FEATURE_LOGINUID_IMMUTABLE bit.
The return value is <= 0 on error, otherwise it is the netlink sequence id number.
audit_set_feature(3), audit_open(3).
