DESCRIPTION
The openpam_log function logs messages using syslog(3). It is primarily
intended for internal use by the library and modules.
The level argument indicates the importance of the message. The follow‐
ing 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(3) priority of
LOG_DEBUG.
PAM_LOG_VERBOSE Information about the progress of the authentication
process, or other non-essential messages. These mes‐
sages are logged with a syslog(3) priority of
LOG_INFO.
PAM_LOG_NOTICE Messages relating to non-fatal errors. These mes‐
sages are logged with a syslog(3) priority of
LOG_NOTICE.
PAM_LOG_ERROR Messages relating to serious errors. These messages
are logged with a syslog(3) priority of LOG_ERR.
The remaining arguments are a printf(3) format string and the correspond‐
ing arguments.
