QTMTB 44 - Correction to SetMediaDataRef, short, not pointer (1-Aug-95)

The online version of IM-QT on the QT2.0 CD defines the interface for the SetMediaDataRef function to be:

  pascal OSErr SetMediaDataRef(Media theMedia, short index, Handle dataRef,
                        OSType dataRefType);

which is also what the prototype in the include file says.

But the actual description for the "index" field says:

"Contains a pointer to a short integer. The Movie Toolbox returns
the index value that is assigned to the new data reference...

This is wrong. SetMediaDataRef returns a short, not a pointer (as defined in the APIs).
