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 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(3) 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(3) priority of
LOG_INFO
.
-
-
PAM_LOG_NOTICE
- Messages relating to non-fatal errors. These messages 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
corresponding arguments.
The
openpam_log() function does not modify the value of
errno.
