其中，这些操作的操作数（type）
可以是1,2,4或8字节长度的int类型，即：
int8_t / uint8_t
int16_t / uint16_t
int32_t / uint32_t
int64_t / uint64_t
type __sync_fetch_and_add (type *ptr, type value);
type __sync_fetch_and_sub (type *ptr, type value);
type __sync_fetch_and_or (type *ptr, type value);
type __sync_fetch_and_and (type *ptr, type value);
type __sync_fetch_and_xor (type *ptr, type value);
type __sync_fetch_and_nand (type *ptr, type value);
type __sync_add_and_fetch (type *ptr, type value);
type __sync_sub_and_fetch (type *ptr, type value);
type __sync_or_and_fetch (type *ptr, type value);
type __sync_and_and_fetch (type *ptr, type value);
type __sync_xor_and_fetch (type *ptr, type value);
type __sync_nand_and_fetch (type *ptr, type value);
PS：
bool __sync_bool_compare_and_swap (type *ptr, type cmpValue,type newval) type __sync_val_compare_and_swap (type *ptr, type cmpValue,type newval) type __sync_lock_test_and_set (type *ptr, type value) void __sync_lock_release (type *ptr)
