EXTENSION_LOGGER_DESCRIPTOR Struct Reference

#include <extension.h>

Public Attributes
const char *(*	get_name )(void)
void(*	log )(EXTENSION_LOG_LEVEL severity, const void *client_cookie, const char *fmt,...)

Detailed Description

Log extensions should provide the following rescriptor when they register themselves. Please note that if you register a log extension it will <u>replace</u> old one. If you want to be nice to the user you should allow your logger to be chained.

Please note that the memcached server will not call the log function if the verbosity level is too low. This is a perfomance optimization from the core to avoid potential formatting of output that may be thrown away.
