Question

我试图将#include <vector>添加到我的MFC项目中。它编译，但我得到以下警告（只是其中一些，实际列表更长）：

1>c:\program files (x86)\microsoft visual studio 9.0\vc\include\cstdio(49) : warning C4995: 'gets': name was marked as #pragma deprecated
1>c:\program files (x86)\microsoft visual studio 9.0\vc\include\cstdio(53) : warning C4995: 'sprintf': name was marked as #pragma deprecated
1>c:\program files (x86)\microsoft visual studio 9.0\vc\include\cstdio(56) : warning C4995: 'vsprintf': name was marked as #pragma deprecated
1>c:\program files (x86)\microsoft visual studio 9.0\vc\include\cstring(22) : warning C4995: 'strcat': name was marked as #pragma deprecated
1>c:\program files (x86)\microsoft visual studio 9.0\vc\include\cstring(23) : warning C4995: 'strcpy': name was marked as #pragma deprecated
1>c:\program files (x86)\microsoft visual studio 9.0\vc\include\cwchar(36) : warning C4995: 'swprintf': name was marked as #pragma deprecated
1>c:\program files (x86)\microsoft visual studio 9.0\vc\include\cwchar(37) : warning C4995: 'vswprintf': name was marked as #pragma deprecated
1>c:\program files (x86)\microsoft visual studio 9.0\vc\include\cwchar(39) : warning C4995: 'wcscat': name was marked as #pragma deprecated
1>c:\program files (x86)\microsoft visual studio 9.0\vc\include\cwchar(41) : warning C4995: 'wcscpy': name was marked as #pragma deprecated

我可以通过这样做来保持沉默：

#pragma warning(push)
#pragma warning(disable: 4995)
#include <vector>
#pragma warning(pop)

但我很想知道为什么图书馆会引起这些警告？除了抑制警告之外，还有更好的解决方法吗？

Answer 1

此警告表示已标记为已过时的功能，在将来的版本中可能不再支持该功能。

所以你可以有两种方法来处理它：首先是你使用的方式，用pragma标记它，或者你可以使用它们的安全版本。

例如，Strcpy有一个名为StringCchCopy / StringCbCopy的相应函数，get有get_s。您可以从MSDN找到它们。

祝你好运。：）
