这个类型,如果在32bit环境下(ILP32),可能是一个无符号uint32,但是在64bit环境(LP64),例如我这边的环境,一般都是有符号的int64(long),也从侧面说明,在条件允许的情况下,即便是C语言接口,系统调用还是倾向于用有符号数的 Linux的系统调用会通过返回值来表示错误,lseek的返回值说明就是: Upon successful completion...
size_t顾名思义，是用来描述容器容量/内存空间大小的。这些数值并不可能取负数——凡让它取了负数，就...
long a[50]; unsigned char size = sizeof (a); produces the warnings: warning: 64-bit constant truncated to 8 bits by assignment warning: initializer does not fit or is out of range: 0x190
Looks like test is broken for other reasons in Python 3; I'll look into fixing that. In the meantime, can you see if the test passes on Python 2? Note that it doesn't for me, but your initial error report suggests that something like it passed for you.Contributor nbecker commented o...
我希望能够在我的项目中使用大的正整数(8字节),即使sizeof(unsigned long)在我的系统中产生8,我读到在大多数系统中unsigned long只有4个字节,我决定尝试一下unsignedlong,因为它保证至少是8个字节。我的代码只能在64位的debian机器上运行,其中unsigned long将是8个字节。可移植性不是一个大问题。在这种情况下,使...

They are both 64-bit processors. On the mac, the size of an unsigned long is 4 bytes and the size of an unsigned long long is 8 bytes. Whereas, on the Ubuntu machine both types come out to 8 bytes. Note that I used sizeof() to get the sizes. I was wondering if someone could...
int8_t、int16_t、int32_t、int64_t、size_t和ssize_t的区别 位数也不同,size_t是无符号数,ssize_t是有符号数。在32位机器中定义为:typedefunsignedintsize_t; (4个字节)在64位机器中定义为:typedef...公众号:CppCodingint_tint_t是一个大类,不同的机器有不同的字长,所以采用typedef的形式,便于后期...
