Fprintf VS _ftprintf [英] Fprintf VS _ftprintf

问题描述

两者的输入参数几乎相同:

both have almost same input parameters:

int _ftprintf( FILE *stream, const _tchar *format [, argument ]...)

int fprintf(FILE *stream, const char *format, ...)

两种格式的产品之间有什么区别? 我应该何时使用它们?

What is the difference between the two format agruments? When should I use each?

推荐答案

_tprintf和_ftprintf与TCHAR格式字符串一起使用. TCHAR只是一个宏，根据是否定义了_UNICODE宏，它会自动展开为char或wchar_t.

_tprintf and _ftprintf are to be used with TCHAR format strings. TCHAR is just a macro, which unwraps into either char or wchar_t, depending on whether is the _UNICODE macro defined.

因此，基本上，如果您未定义_UNICODE，则_ftprintf将等同于fprintf，否则将等同于fwprintf.

So, basically, if you don't have _UNICODE defined, _ftprintf will be equivalent to fprintf, otherwise it will be equivalent to fwprintf.
