ITMSPAddress::ShutdownMSPCall method (msp.h)

  • Article

The ShutdownMSPCall method is called when the call object is being destroyed.

Syntax

HRESULT ShutdownMSPCall(
  [in] IUnknown *pStreamControl
);

Parameters

[in] pStreamControl

Pointer to IUnknown interface for the call's ITStreamControl.

Return value

This method can return one of these values.

Value Meaning
S_OK
 Method succeeded.
E_POINTER
 The pStreamControl parameter is not a valid pointer.
E_INVALIDARG
 The pStreamControl parameter does not point to a valid ITStreamControl interface.

Remarks

This method is not automatically invoked when a call enters the disconnect state. The paired TSP of the MSP should notify the MSP of this call state change, but, because applications may retain the call object for information logging purposes after a disconnect, shutdown should not be called until the call object itself is released.
