Draws a list of cels (one or more) to the bitmaps of a screen.
Err DrawScreenCels (Item screenItem,CCB *ccb)
DrawScreenCels traverses the list of bitmaps associated with the screen specified by the screenItem argument, calling DrawCels()
for each bitmap. When this call returns, all cels are rendered into all bitmaps of the screen.
The call returns 0 if successful or an error code (a negative value) if an error occurs.
Folio call implemented in Graphics folio V20. It became an SWI in Graphics folio V24.
