_stprintf & _sntprintf 过期了怎么办？

Update: 微软网站上面两篇关于软件安全的文章提到SafeCRT liberaries, 在VS2005开始提供，可以试试： http://download.microsoft.com/download/1/1/d/11d125ba-d95c-480a-8a99-4700089a93e9/DSK302.ppt http://download.microsoft.com/download/2/3/2/232d5429-e8c4-40da-9d90-bd33bab01e6f/DEV380-linhua.pdf 这两篇文章本身也是不错的资料。 ---------------------------------------------------------------------------------------- 今天做了一个小测试程序，结果发现_stprintf过期了，再试试发现_sntprintf也过期了 error C4995: '_sntprintf': name was marked as #pragma deprecated error C4995: '_snwprintf': name was marked as #pragma deprecated 真tmd的晕，过期了也这么霸道，根本就不告诉你过期了怎么办， 其实编译器只要给个链接到新的函数上面可以节省程序员好多时间 暗骂编译器n遍以后，上google搜了一下，发现了一个基本上对应于_sntprintf的函数：StringCchPrintf HRESULT StringCchPrintf( LPTSTR pszDest, size_t cchDest, LPCTSTR pszFormat, ... ); 该函数返回如下结果以证明其清白（安全） S_OK There was sufficient space for the result to be copied to pszDest without truncation, and the buffer is null-terminated. STRSAFE_E_INVALID_PARAMETER The value in cbDest is 0 or larger than STRSAFE_MAX_CCH * sizeof(TCHAR). STRSAFE_E_INSUFFICIENT_BUFFER The copy operation failed due to insufficient buffer space. The destination buffer contains a truncated, null-terminated version of the intended result. Where truncation is acceptable, this is not necessarily a failure condition. 不爽的话也可以试试StringCbPrintf，差不多，区别在于byte & TCHAR 顺便看了一下该头文件(Strsafe.h)中的其他函数，copy列表如下： Strsafe.h function Replaces StringCchCat StringCchCatEx strcat, wcscat StringCchCatN StringCchCatNEx strncat StringCchCopy StringCchCopyEx strcpy, wcscpy StringCchCopyN StringCchCopyNEx strncpy StringCchGets StringCchGetsEx gets, _getws StringCchPrintf StringCchPrintfEx sprintf, swprintf, wsprintf, _snprintf, _snwprintf StringCchVPrintf StringCchVPrintfEx vsprintf, vswprintf, _vsnprintf, _vsnwprintf StringCchLength strlen
