In case an error is encountered, the script logs the error to the configured table in MySQL, in the 'event_log' table, mentioning "err-pmu-N" (where N is the error number) in the 'event' column, populating the 'device_username' column with the user's username, leaving the other columns empty, and exits immediately, returning the error number as exit code. The error is logged to MySQL only if the script is running as root. In case access is available to the script's stdout and stderr, a description of the error message is also printed (and the script is quite verbose about what's happening if cfg_verbose is set to 1), in case not, it is possible to look in the script's code for calls to the pam_to_mysql_update_error_message_close() function, identify the call where the error number in question is passed to the function, and the error description can be found in the same function call. The configurable options can be found at the top of the script.
