strlen
基本解释
- n.字符长度
英汉例句
- The strlen() function returns the length of a string.
函数的作用是:返回字符串长度。 - We can use this fact to write another version of strlen, which computes the length of a string.
如果要更详细的了解,建议还是把这章细读一遍。 - When we call strlen, it returns the number of characters in a zero-terminated array of single-byte characters.
许多年来,许多人一直将字符串作为一系列单字节字符来进行编码,并在结尾处加上0. - The strlen() call was there only to make sure the value is actually accessed....
如果在声明中用表达式的结果对其赋值会导致解析错误。 - BTW: if you want to call recv() with the maximal length of return_msg, please use sizeof(return_msg) instead of strlen(return_msg).
但是就是不明白为什么如果接受的长度大于了实际返回的长度就可能出现我上述的那种情况呢(好像不是所有的时候都那样)!
