| 23 | * This header file describes the structures of the file format for "fat" | |
| 24 | * architecture specific file (wrapper design). At the begining of the file | |
| 25 | * there is one fat_header structure followed by a number of fat_arch | |
| 26 | * structures. For each architecture in the file, specified by a pair of | |
| 27 | * cputype and cpusubtype, the fat_header describes the file offset, file | |
| 28 | * size and alignment in the file of the architecture specific member. | |
| 29 | * The padded bytes in the file to place each member on it's specific alignment | |
| 30 | * are defined to be read as zeros and can be left as "holes" if the file system | |
| 31 | * can support them as long as they read as zeros. | |
| 32 | * | |
| 33 | * All structures defined here are always written and read to/from disk | |
| 34 | * in big-endian order. | |
