Re: [Alephmodular-devel] Macintosh oddity: GetCTable(8)?

[Chris B. <ce...@ma...>]

It would appear that this is correct behavior. It may have been 
depreciated some time ago (carbon? system 9?) however there seems to be 
a fair bit of code around which uses this approach and run fine. I have 
a suspicion that if we looked up the original inside mac series it 
would specify 8 as being the system-standard 256 color table and 40 
(8+32) as being the standard 256 grayscale table. 'course i don't have 
it in front of me at work so ymmv :-)

that said, you may as well fix it to use the new constants. sooner or 
later they may drop the old stuff.
