void netsnmp_logging_restart

(

void

hmm, don't zero status isn't saved.. i think it's safer not to overwrite, in case a hup is just to re-read config files...

int snmp_get_do_logging

(

void

)

Is logging done?

Returns:

Returns 0 if logging is off, 1 when it is done.

Definition at line 576 of file snmp_logging.c.

int snmp_log	(	int	priority,
		const char *	format,
			...
	)

This snmp logging function allows variable argument list given the specified format and priority.

Calls the snmp_vlog function. The default logfile this function writes to is /var/log/snmpd.log.

See also:

snmp_vlog

Examples:

delayed_instance.c.

Definition at line 1423 of file snmp_logging.c.

int snmp_vlog	(	int	priority,
		const char *	format,
		va_list	ap
	)

This snmp logging function allows variable argument list given the specified priority, format and a populated va_list structure.

The default logfile this function writes to is /var/log/snmpd.log.

Parameters:

priority	is an integer representing the type of message to be written to the snmp log file. The types are errors, warning, and information. The error types are: LOG_EMERG system is unusable LOG_ALERT action must be taken immediately LOG_CRIT critical conditions LOG_ERR error conditions The warning type is: LOG_WARNING warning conditions The information types are: LOG_NOTICE normal but significant condition LOG_INFO informational LOG_DEBUG debug-level messages
format	is a pointer to a char representing the variable argument list format used.
ap	is a va_list type used to traverse the list of arguments.

Returns:

Returns 0 on success, -1 when the code could not format the log- string, -2 when dynamic memory could not be allocated if the length of the log buffer is greater then 1024 bytes. For each of these errors a LOG_ERR messgae is written to the logfile.
