c – atoi() – 字符串到int

我读到atoi()已被弃用,它相当于：

(int)strtol(token_start,(char **)NULL,10);

这是否意味着我应该使用上面而不是atoi(chr)或者它只是说它们是等价的？

解决方法

它确实在Apple的 Mac OS X Manual Page for atoi(3)(以及BSD手册页)中说过atoi已被弃用.

The atoi() function has been deprecated by strtol() and should not be
used in new code.

我会因为这个原因使用strtol()等效,但我怀疑你不得不担心atoi()被删除.

* The atoi function is not thread-safe and also not async-cancel safe.
