Chapter 2 - Scrap Manager / Using the Scrap Manager

Getting Information About the Scrap

To get information about the scrap, you can use the InfoScrap function. The InfoScrap function returns a pointer to a scrap information record. (See "The Scrap Information Record" on page 2-32 for detailed information on the fields of this record.) The information in the scrap information record provides

• the size (in bytes) of the scrap
• a handle to the scrap if it's in memory
• a count, or number that your application can use to determine whether the contents of the scrap have changed
• the location of the scrap (whether in memory or on disk)
• the filename of the scrap when it is on the disk

For example, this code uses the InfoScrap function to get the size of the scrap.

VAR
   curScrapInfoPtr:  PScrapStuff;
   curScrapSize:     LongInt;

   curScrapInfoPtr := InfoScrap;
   curScrapSize := curScrapInfoPtr^.scrapSize;
