At the begining of the file * there is one fat_header structure followed by a number of fat_arch * structures. For each architecture in the file, specified by a pair of * cputype and cpusubtype, the fat_header describes the file offset, file * size and alignment in the file of the architecture specific member. * The padded bytes in the file to place each member on it's specific alignment * are defined to be read as zeros and can be left as "holes" if the file system * can support them as long as they read as zeros. * * All structures defined here are always written and read to/from disk * in big-endian order. */ /* * <mach/machine.h> is needed here for the cpu_type_t and cpu_subtype_t types * and contains the constants for the possible values of these types. */ #include <mach/machine.h> #include <architecture/byte_order.h> #define FAT_MAGIC 0xcafebabe #define FAT_CIGAM NXSwapLong(FAT_MAGIC) struct fat_header { unsigned long magic; /* FAT_MAGIC */ unsigned long nfat_arch; /* number of structs that follow */ }; struct fat_arch { cpu_type_t cputype; /* cpu specifier (int) */ cpu_subtype_t cpusubtype; /* machine specifier (int) */ unsigned long offset; /* file offset to this object file */ unsigned long size; /* size of this object file */ unsigned long align; /* alignment as a power of 2 */ };
