OPENPAM_LOG(3)						   BSD Library Functions Manual 					    OPENPAM_LOG(3)

openpam_log -- log a message through syslog
Pluggable Authentication Module Library (libpam, -lpam)
#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 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.
