The SnmpSvcGetUptime function retrieves the number of centiseconds that the SNMP service has been running. This function is an element of the SNMP Utility API.
DWORD SnmpSvcGetUptime();
This function has no parameters.
The function returns a DWORD value that is the number of centiseconds the SNMP service has been running.
An extension agent should call the SnmpSvcGetUptime function only if the extension agent DLL is loaded within the address space of the SNMP service.
The SNMP extension agent DLL is encouraged to use the SnmpSvcGetUptime function to retrieve the number of centiseconds that the SNMP service has been running. Extension agents should use SnmpSvcGetUptime rather than calculate the uptime using the dwUptimeReference parameter. The service passes this parameter to the extension agent as the result of a call to the SnmpExtensionInit function. Because the dwUptimeReference parameter stores the elapsed time as a DWORD value in milliseconds, the time can wrap to zero and reflect an inaccurate time interval.
An extension agent that sends traps must initialize the timeStamp parameter to the SnmpExtensionTrap function with the value returned by a call to the SnmpSvcGetUptime function.
