RpcAsyncGetCallStatus function (rpcasync.h)
The client calls the RpcAsyncGetCallStatus function to determine the current status of an asynchronous remote call.
Syntax

PRPC_ASYNC_STATE pAsync
);
Parameters

Pointer to the RPC_ASYNC_STATE structure that contains asynchronous call information.
Return value
| Value | Meaning |
|---|---|
|
The call was completed successfully. |
|
The asynchronous call handle is not valid. |
