ZeroScrap
ZeroScrap Empty the desk scrap and bump scrapCount
#include <Scrap.h> Scrap Manager
long ZeroScrap( );
returns an Error Code; 0=no error
ZeroScrap initializes the desk scrap and purges any data currently in it. It
changes the global variable ScrapInfo. scrapCount to let DAs and others know
that the contents of the scrap has been changed.
Returns: a long integer Error Code; 0 indicates no error.

Notes: Call ZeroScrap before using PutScrap to store an item. If you are
storing two or more types of the data (e.g. a 'PICT' item and a 'TEXT' item),
call ZeroScrap only before storing the first type.
This modifies the ScrapInfo. scrapCount variable in an arbitrary fashion.
By watching for changes in this variable, you can see if DAs or other
applications have put new data into the scrap.
Early in the application, you should call InfoScrap, and if the scrapState
field of the returned ScrapStuff structure is less than 0, then call
ZeroScrap to initialize the scrap.
