+/**
+ * The =openpam_log function logs messages using =syslog.
+ * It is primarily intended for internal use by the library and modules.
+ *
+ * The =level argument indicates the importance of the message.
+ * The following levels are defined:
+ *
+ *	=PAM_LOG_DEBUG:
+ *		Debugging messages.
+ *		These messages are normally not logged unless the global
+ *		integer variable :_openpam_debug is set to a non-zero
+ *		value, in which case they are logged with a =syslog
+ *		priority of =LOG_DEBUG.
+ *	=PAM_LOG_VERBOSE:
+ *		Information about the progress of the authentication
+ *		process, or other non-essential messages.
+ *		These messages are logged with a =syslog priority of
+ *		=LOG_INFO.
+ *	=PAM_LOG_NOTICE:
+ *		Messages relating to non-fatal errors.
+ *		These messages are logged with a =syslog priority of
+ *		=LOG_NOTICE.
+ *	=PAM_LOG_ERROR:
+ *		Messages relating to serious errors.
+ *		These messages are logged with a =syslog priority of
+ *		=LOG_ERR.
+ *
+ * The remaining arguments are a =printf format string and the
+ * corresponding arguments.
