audit_set_rate_limit - Set audit rate limit
int audit_set_rate_limit (int fd, int limit);
audit_set_rate_limit will set the maximum number of messages that the kernel
will send per second. This can be used to throttle the rate if systems become
unresponsive. Of course the trade off is that events will be dropped. The
default value is 0, meaning no limit.
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.
