SNMP Extension API Functions (Windows CE 5.0)
The SNMP Extension-Agent API functions define the interface between the SNMP service and SNMP extension-agent DLLs. Applications use these functions to resolve the variable bindings that are specified by incoming SNMP PDUs. The following table shows the SNMP Extension API functions that are supported by Windows CE and should be implemented by an extension agent in order to work with the master agent.
| Function | Description |
|---|---|
| SnmpExtensionClose | Deallocates resources and terminates operations. |
| SnmpExtensionInit | Initializes the SNMP extension-agent DLL. |
| SnmpExtensionInitEx | Identifies any additional management information base (MIB) subtrees that the SNMP extension agent supports. Implementation is optional. |
| SnmpExtensionQuery | Resolves SNMP requests that contain variables within one or more of the registered MIB subtrees of the SNMP extension agent. |
| SnmpExtensionQueryEx | Processes SNMP requests that specify variables in one or more MIB subtrees that are registered by SNMP extension agents. Implementation is optional. |
| SnmpExtensionTrap | Retrieves information that the service requires for generating traps for the SNMP extension agent. The service calls this function only after the extension agent sets the trap-event handle to the signaled state during a call to the SnmpExtensionInit function. |
