Answer 1

lispobj不是结构,只是一个typedef.它src/runtime/runtime.h在第234行之后定义:

#if 64 == N_WORD_BITS
#define LOW_WORD(c) ((pointer_sized_uint_t)c)
#define OBJ_FMTX "lx"
typedef uintptr_t lispobj;
#else
#define OBJ_FMTX "x"
#define LOW_WORD(c) ((long)(c) & 0xFFFFFFFFL)
/* fake it on alpha32 */
typedef unsigned int lispobj;
#endif
