Register a callback that will be fired every time the app is expected to draw a frame.
GLVIEW_API int glview_register_frame_callback(frame_callback frame_callback)
The function to call after all events have been processed, and the app is expected to draw the frame.
The display callback is initially set by the glview_initialize() function and is the only mandatory callback. An app can use this function to set a different display callback. A display callback must always be registered and valid. Setting the callback to NULL is invalid and will fail.
- EFAULT: Attempt to register a NULL display callback. In the event of GLVIEW_FAILURE, the previously registered frame_callback will remain.
