2 | ** Unix-HFS file interface including maping file extensions to TYPE/CREATOR |
3 | ** |
4 | ** Adapted from mkhfs routines for mkhybrid |
5 | ** |
6 | ** James Pearson 1/5/97 |
7 | ** Bug fix JCP 4/12/97 |
8 | ** Updated for 1.12 and added more Unix HFS filetypes. JCP 21/1/98 |
9 | ** |
10 | ** Things still to de done: |
11 | ** |
12 | ** Check SGI (XINET) structs |
13 | ** Check file size = finder + rsrc [+ data] is needed |
14 | ** AppleSingle/Double version 2? |
15 | ** Clean up byte order swapping. |
