怎么判断当前操作系统？？

[ffstudio]

并且如何得到它的system/system32等系统目录？

[gbstar2021]

OSVERSIONINFO VerInfo;
VerInfo.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
GetVersionEx(&VerInfo);
...............

GetSystemDirectory

[jimmey]

UINT GetWindowsDirectory(
LPTSTR lpBuffer, // buffer for Windows directory
UINT uSize // size of directory buffer
);
此函数获得window 目录

UINT GetSystemDirectory(
LPTSTR lpBuffer, // buffer for system directory
UINT uSize // size of directory buffer
);
此函数获得window下system 目录

GetSystemDirectory可以。
UINT GetSystemDirectory(
LPTSTR lpBuffer, // address of buffer for system directory
UINT uSize // size of directory buffer
);

看MSDN中的文档：


dwVersion = GetVersion();

// Get major and minor version numbers of Windows
dwWindowsMajorVersion = (DWORD)(LOBYTE(LOWORD(dwVersion)));
dwWindowsMinorVersion = (DWORD)(HIBYTE(LOWORD(dwVersion)));
// Get build numbers for Windows NT or Win32s
if (dwVersion < 0x80000000) // Windows NT
dwBuild = (DWORD)(HIWORD(dwVersion));
else if (dwWindowsMajorVersion < 4) // Win32s
dwBuild = (DWORD)(HIWORD(dwVersion) & ~0x8000);
else // Windows 95 -- No build numbers provided
dwBuild = 0;
