wglDeleteContext function (wingdi.h)
The wglDeleteContext function deletes a specified OpenGL rendering context.
Syntax
BOOL wglDeleteContext(
HGLRC unnamedParam1
);
Parameters
unnamedParam1
Handle to an OpenGL rendering context that the function will delete.
Return value
If the function succeeds, the return value is TRUE.
If the function fails, the return value is FALSE. To get extended error information, call GetLastError.
Remarks
It is an error to delete an OpenGL rendering context that is the current context of another thread. However, if a rendering context is the calling thread's current context, the wglDeleteContext function changes the rendering context to being not current before deleting it.
The wglDeleteContext function does not delete the device context associated with the OpenGL rendering context when you call the wglMakeCurrent function. After calling wglDeleteContext, you must call DeleteDC to delete the associated device context.
