Function Documentation

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...

Definition at line 632 of file snmp_logging.c.

int snmp_get_do_logging ( void   ) 

Is logging done?

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

Definition at line 489 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 1270 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.
