将C应用程序从AIX移植到Linux-有人知道Linux上是否有等效的mbsinvalid()函数吗？

从AIX页面：

“ mbsinvalid子例程检查S参数指向的字符串以确定字符的有效性.LC_CTYPE类别影响mbsinvalid子例程的行为.”

http://publib.boulder.ibm.com/infocenter/pseries/v5r3/index.jsp?topic=/com.ibm.aix.basetechref/doc/basetrf1/mbsinvalid.htm

谢谢！

解决方法:

将mbstowcs与NULL目标指针一起使用：

If dest is NULL, n is ignored, and the conversion proceeds as above, except that the converted wide characters are not written out to memory, and that no length limit exists.

….

1. An invalid multibyte sequence has been encountered. In this case (size_t) -1 is returned.

(从mbstowcs man page开始).

也就是说,(size_t)-1的结果表示存在无效的多字节序列.
