cppreference.com 创建账户 std::printf,std::fprintf,std::sprintf,std::snprintf 在标头<cstdio>定义 intprintf(constchar*format, ...); (1) intfprintf(std::FILE*stream,constchar*format, ...); (2) intsprintf(char*buffer,constchar*format, ...); ...
这两种不同的返回值都符合C语言标准,因为标准就是Microsoft这些巨头们制定的,当返回结果不一样又互不妥协的时候,那就把两种结果都写进标准吧。 下面是C语言标准库(C standard library)关于vsnprintf,snprintf函数的说明原文https://en.cppreference.com/w/c/io/fprintfhttps://en.cppreference.com/w/c/io/vfpri...
將格式化資料寫入字串。 這些函式有更安全的版本可供使用;請參閱、、_snwprintf_s_snprintf_s_l、。_snprintf_s_snwprintf_s_l 語法 C複製 intsnprintf(char*buffer,size_tcount,constchar*format [, argument] ... );int_snprintf(char*buffer,size_tcount,constchar*format [, argument] .....
