  • 项目

Makes a request to the worker thread and blocks for a response.

  DWORD dw
);

Parameters

  • dw
    Derived class defines the meaning of the parameter.

Return Values

Returns a value that is defined by the derived class.

Remarks

This member function uses a CCritSec object to ensure that only one request is made at a time. It is therefore not valid to call the CAMThread::CallWorker member function from the thread itself or from any member function that is executing in the context of the thread.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
