/**
|
|
* 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_LIBDEBUG:
|
|
* Debugging messages.
|
|
* For internal use only.
|
|
* =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.
