Comments

This function allows the user to store a complete media file in global memory and use it as the source for the playback. The user is responsible for allocating, initializing, and freeing the global memory. However, the user should not free the global memory handle while the play object holds a reference to it. The ResetSource function should be called to stop the play object from accessing the global memory. The SourceType will be set to ltmmPlay_Source_HGlobal.
