The wglGetCurrentDC function obtains a handle to the device context that is associated with the current OpenGL rendering context of the calling thread.
This function has no parameters.
If the calling thread has a current OpenGL rendering context, the function returns a handle to the device context associated with that rendering context by means of the wglMakeCurrent function. Otherwise, the return value is NULL.
You associate a device context with an OpenGL rendering context when it calls the wglMakeCurrent function. You can use the wglGetCurrentContext function to obtain a handle to the calling thread's current OpenGL rendering context.
