AddIconToSuite
AddIconToSuite Add an icon to an icon family
#include <Icons.h> Finder Interface
OSErr AddIconToSuite (theIconData, theSuite, theType );
Handle theIconData ; handle to the icon to add
Handle theSuite ; icon family to receive the icon
ResType theType ; location where icon should be added
returns Error Code; 0 = no error
AddIconToSuite adds the data in theIconData into the the icon family
referenced by theSuite at the location reseved for theType of icon data.
AddIconToSuite will replace any old data in that slot without disposing of it,
so you may want to call GetIconFromSuite to obtain the old handle (if any),
to dispose. AddIconToSuite is use most often with NewIconSuite to fill an
empty family after it has been created.

Notes: This routine is not currently documented in MPW header files (hence, it is
not in any THINK C or THINK Pascal header file either). The information
given above comes from Macintosh Technical Note #306. This tech. note
also gives the inline glue for the call as follows:
pascal OSErr AddIconToSuite (Handle theIconData, Handle theSuite,
ResType theType) = {0x303C, 0x0608, 0xABC9};
