26 | * This header file describes the structures of the file format for "fat"␊ |
27 | * architecture specific file (wrapper design). At the begining of the file␊ |
28 | * there is one fat_header structure followed by a number of fat_arch␊ |
29 | * structures. For each architecture in the file, specified by a pair of␊ |
30 | * cputype and cpusubtype, the fat_header describes the file offset, file␊ |
31 | * size and alignment in the file of the architecture specific member.␊ |
32 | * The padded bytes in the file to place each member on it's specific alignment␊ |
33 | * are defined to be read as zeros and can be left as "holes" if the file system␊ |
34 | * can support them as long as they read as zeros.␊ |
35 | *␊ |
36 | * All structures defined here are always written and read to/from disk␊ |
37 | * in big-endian order.␊ |
