MIBEntryGetFirst callback function
The routing protocol calls MIBEntryGetFirst to execute a Get First request of the router manager or a peer protocol DLL. Implement this function to handle SNMP-style requests.
Syntax
DWORD CALLBACK MIBEntryGetFirst(
_In_ DWORD dwRoutingPid,
_In_ DWORD InputDataSize,
_In_ PVOID InputData,
_Inout_ DWORD *OutputDataSize,
_Out_ PVOID OutputData
);
Parameters
dwRoutingPid [in]
Specifies the identifier of the DLL that should process this request. This parameter can be the identifier of the router manager or the identifier of a routing protocol.InputDataSize [in]
Specifies the size, in bytes, of the data to pass with the Get First request.InputData [in]
Pointer to the data to pass with the Get First request.OutputDataSize [in, out]
A pointer to a DWORD variable:On input, this variable specifies the size, in bytes, of the output buffer.
On output, this variable receives the size, in bytes, of the data placed in the output buffer. If the initial size is not large enough, this variable contains the buffer size required to hold all of the output data.
OutputData [out]
Pointer to a buffer that receives the data from the MIB entry.
