Parameter Description

This parameter provides a convenient way of declaring a user-defined context associated with a MultiCam surface using a pointer value. This context can be easily retrieved from the surface handle in a callback or waiting function.

For backward compatibility, it is still possible to use a 32-bit integer value instead of a pointer.
