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