Parameters
userParam:long

the global reference pointer

registerContextCallbackARBback to summary
pack-priv static void registerContextCallbackARB(final long userParam)

Associates the current OpenGL context with the specified global reference. If there is no context current, the global reference is deleted and an exception is thrown. Any previous callback registrations will be cleared.

Parameters
