125 * The =openpam_log function logs messages using =syslog. It is primarily
126 * intended for internal use by the library and modules.
128 * The =level argument indicates the importance of the message. The
129 * following levels are defined:
132 * Debugging messages. These messages are normally not
133 * logged unless the global integer variable :_openpam_debug
134 * is set to a non-zero value, in which case they are logged
135 * with a =syslog priority of =LOG_DEBUG.
137 * Information about the progress of the authentication
138 * process, or other non-essential messages. These messages
139 * are logged with a =syslog priority of =LOG_INFO.
141 * Messages relating to non-fatal errors. These messages are
142 * logged with a =syslog priority of =LOG_NOTICE.
144 * Messages relating to serious errors. These messages are
145 * logged with a =syslog priority of =LOG_ERR.
147 * The remaining arguments are a =printf format string and the
148 * corresponding arguments.
