: 推 halajohn:恩, wcscpy_s 这类 _s 的 function, 是定义在 11/26 09 : → halajohn:ISO/IEC TR 24731 中, 这些 function 的规范更严谨, 11/26 09 : → halajohn:好处也更多. 我当初也很惊讶 VC2005 实现了这套. 11/26 09 : → halajohn:不只 vc2005 有, openwatcom 1.5 以後也都有. 11/26 09 : → halajohn:这算是 c library 的 extension. 跟 compiler 没关. 11/26 09 : → halajohn:要怪就怪 glibc 怎麽进度这麽慢吧. 11/26 09 : → halajohn:anyway, 要改回没有 _s 的方法比加上 _s 还要来的简单. 11/26 09 : → godfat:可以考虑回文 @@; 翻了一下，dinkumware 好像也没做... 11/26 10 : → godfat:改天再查查看有谁做好了 @@ 11/26 10 说是改天不过好奇起来就查了 :o ISO/IEC TR 24731 Abstract ISO/IEC TR 24731-1:2007 provides alternative functions for the C Library (as defined in ISO/IEC 9899:1999) that promote safer, more secure programming. The functions verify that output buffers are large enough for the intended result, and return a failure indicator if they are not. Optionally, failing functions call a "runtime-constraint handler" to report the error. Data is never written past the end of an array. All string results are null terminated. In addition, the functions in ISO/IEC TR 24731-1:2007 are re-entrant: they never return pointers to static objects owned by the function. ISO/IEC TR 24731-1:2007 also contains functions that address insecurities with the C input-output facilities. 好像是今年八月出版的？其实我觉得说这是标准也没错啦，只是... XD 不清楚 C 有没有像 C++ 的 boost 那种东西？boost 就有做半套 TR1, 总比完全没有好 :o 习惯把标准看成 C99, C++98, C++03 等... 所以没想到 TR and dinkumware 似乎有以下 TR: <hardware> [added with TR18015] -- for writing portable I/O hardware drivers in C++ <iohw.h> [added with TR18015/TR18037] -- for writing portable I/O hardware drivers in C <stdfix.h> [added with TR18037] -- for performing fixed-point arithmetic in C <uchar.h> [added with TR19769] -- for manipulating 16-bit and 32-bit Unicode wide characters in C 还有 C++ 社群俗称的 TR1... 不知道全部有多少个？ :o -- 生死去来、棚头傀儡、一线断时、落落磊磊 《花镜》－世阿弥 --
