MakeIconCache

Create an empty icon cache

#include <Icons.h> Finder Interface

OSErr MakeIconCache (theCache, GetAnIcon, yourDataPtr );

Handle *theCache ; handle to icon family

ProcPtr GetAnIcon ; icon loading procedure

returns Error Code; 0 = no error

MakeIconCache returns an empty icon cache handle in theSuite and

associates with it the icon loading procedure in GetAnIcon and the data in

yourDataPtr with it. All members of the family are set to NIL.

Notes: MakeIconCache takes a ProcPtr parameter, GetAnIcon. The ProcPtr

should have the following format:

Handle GetAnIcon (ResType theType, Ptr yourDataPtr);

This function should return either the icon data to be used to draw or nil to

signify that this entry in the icon cache does not exist. See

Drawing Icons with System 7 for more on icon caches.

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:

yourDataPtr ) = {0x303C, 0x0604, 0xABC};
