ITMSPAddress::ReceiveTSPData method (tapi3.h)
The ReceiveTSPData method is called by TAPI 3 when the TSP sends asynchronous data to the MSP. If the TSP sends the LINE_SENDMSPDATA message with the htCall set to NULL, pMSPCall will be NULL. If the TSP does specify the htCall, pMSPCall will correspond to the call created in CreateMSPCall.
HRESULT ReceiveTSPData( IUnknown *pMSPCall, BYTE *pBuffer, DWORD dwSize );
Pointer to IUnknown interface of the MSP Call object.
[in, size_is(dwSize)] Pointer to opaque buffer from the TSP.
Size, in bytes, of pBuffer.
This method can return one of these values.
||The pMSPCall or pBuffer parameter is not a valid pointer.|
||The pMSPCall parameter is NULL.|
||The pMSPCall parameter does not point to a valid interface.|
||Insufficient memory exists to perform the operation.|
The MSP must free memory in pBuffer.
The semantics of the data passed in the buffer are specific to each TSP/MSP pair. This method simply dispatches the received buffer to the address (pMSPCall == NULL) or the indicated call (pMSPCall != NULL).
