CoIsHandlerConnected (Compact 2013)

  • Article

3/26/2014

This function determines whether a remote object is connected to the corresponding in-process object.

Syntax

BOOL CoIsHandlerConnected(
  LPUNKNOWN pUnk
);

Parameters

  • pUnk
    [in] Pointer to the controlling IUnknown interface on the remote object.

Return Value

  • TRUE
    The object is not remote or that it is remote and is still connected to its remote handler.
  • FALSE
    The object is remote and is invalid (no longer connected to its remote handler).

Remarks

The CoIsHandlerConnected function determines the status of a remote object. Your application can use it to determine when to release a remote object. The application specifies the remote object by giving the function a pointer to its controlling IUnknown interface (the pUnk parameter).

A TRUE returned from the function indicates either that the specified object is not remote, or that it is remote and is still connected to its remote handler.

A FALSE returned from the function indicates that the object is remote but is no longer connected to its remote handler; in this case, the caller should respond by releasing the object.
