openpam_log -- log a message through syslog
#include <sys/types.h> #include <security/pam_appl.h> #include <security/openpam.h> void openpam_log(int level, const char *fmt, ...);
The openpam_log() function logs messages using syslog(3). It is primar- ily 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_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 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. The openpam_log() function does not modify the value of errno.
