Discussion

This function creates a file handle that can be used to read asynchronously from SPU memory.

This file handle can be used with the BinkOpen function to play a Bink movie out of SPU RAM, or with the AIL_open_stream function to play a sound file out of SPU RAM.

You can copy data from the SPU to the IOP by using these kinds of file handles and then using the async read function with the appropriate destination pointer type.

You don't have to close this type of file handle.
