 * Note that these structures can end up in both a 32-bit and 64-bit libproc.
 * Therefore, one should generally avoid using types whose size change between
 * ILP32 and LP64 and instead use the correct fixed width type. eg. long should
 * be int32_t and int64_t as appropriate to whether it's a 32-bit or 64-bit
 * structure.
