wglGetCurrentDC
The wglGetCurrentDC function obtains a handle to the device context that is associated with the
current OpenGL rendering context of the calling thread.
HDC wglGetCurrentDC(VOID);
Parameters
This function has no parameters.
Return Values
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.
Remarks
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.
Requirements
Windows NT/2000: Requires Windows NT 3.5 or later.
Windows 95/98: Requires Windows 95 or later. Available as a redistributable for Windows 95.

wglGetCurrentContext
The wglGetCurrentContext function obtains a handle to the current OpenGL rendering context of the
calling thread.
HGLRC wglGetCurrentContext(VOID);
Parameters
This function has no parameters.
Return Values
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.
