       An event object may be created by linking to an OpenGL sync object. Completion of such an event object is
       equivalent to waiting for completion of the fence command associated with the linked GL sync object.

       Returns a valid OpenCL event object and errcode_ret is set to CL_SUCCESS if the event object is created
       successfully. Otherwise, it returns a NULL value with one of the following error values returned in
       errcode_ret:

       •   CL_INVALID_CONTEXT if context is not a valid context or was not created from a GL context.

       •   CL_INVALID_GL_OBJECT if sync is not the name of a sync object in the GL share group associated with
           context.
