Routine Description:

This routine is the callback routine for an NCP which has no

|
return parameters and the caller blocks waiting for a response.

Arguments:
|
|
|
|
pIrpContext - A pointer to the context information for this IRP.
|
|
|
|
BytesAvailable - Actual number of bytes in the received message.
|
|
|
|
RspData - Points to the receive buffer.
|
|
|
|
Return Value:
|
|
|
|
NTSTATUS - Status of the operation.
