wglGetCurrentContext function (wingdi.h)
The wglGetCurrentContext function obtains a handle to the current OpenGL rendering context of the calling thread.
Syntax
HGLRC wglGetCurrentContext();
Return value
If the calling thread has a current OpenGL rendering context, wglGetCurrentContext returns a handle to that rendering context. Otherwise, the return value is NULL.
Remarks
The current OpenGL rendering context of a thread is associated with a device context by means of the wglMakeCurrent function. You can use the wglGetCurrentDC function to obtain a handle to the device context associated with the current OpenGL rendering context.
