分享wchar_t 2字节？4字节?在线
今天郁闷至极，记得wchar_t 应该是2字节，但是我的编译器用sizeof(wchar_t)出来的是4。
不知那里的问题。搞的我以为wsccmp函数错了，花了一天的时间。
在gcc中，wchar_t因该是几字节的?或者编译开关如何设定？
在线等待

在GCC上就是4个字节,具体是两个字节还是四个字节是跟编译器相关的,在windows下是两个bytes,
以下文字摘自: What size wchar_t do I need for Unicode?
http://icu.sourceforge.net/docs/papers/unicode_wchar_t.html
The C standard does not specify the exact type for wchar_t. It is compiler dependent and may be 8, 16, or 32 bits wide (on modern machines), signed or unsigned. The choice depends on what encodings are expected to be processed on a particular platform. The standard also does not specify the representation of a multibyte code point with a wchar_t value: it is encoding- and library-dependent (except that a single-byte code point must have the same integer value in char and wchar_t types).

有2字节有4字节的
