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 GetIconCacheData (Handle theCache, Ptr *yourDataPtr)
= {0x303C, 0x041B, 0xABC9};
