.In 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_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.
pam(3), printf(3), syslog(3)
