LIBRARY

     Pluggable Authentication Module Library (libpam, -lpam)

SYNOPSIS

     #include <sys/types.h>

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_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.
