audit_set_pid - Set audit daemon process ID
int audit_set_pid (int fd, int pid);
audit_set_pid tells the kernel what the pid is of the audit daemon. When the pid
is set to 0, the kernel will log all events to syslog. Otherwise it will try
to send events to the netlink connection that has the same pid given by this
function. If for some reason the process goes away, the kernel will
automatically set the value to 0 itself. Usually this function is called by
the audit daemon and not an external program.
The return value is <= 0 on error, otherwise it is the netlink sequence id
number. This function can have any error that sendto would encounter.
