How to get the current user's home directory in Windows
提问by Ullan
How can I get the path to the current User's home directory?
如何获取当前用户主目录的路径？
Ex: In Windows, if the current user is "guest" I need "C:\Users\guest"
例如：在 Windows 中，如果当前用户是“guest”，我需要“C:\Users\guest”
My application will run on most of the Windows versions (XP, Vista, Win 7).
我的应用程序将在大多数 Windows 版本（XP、Vista、Win 7）上运行。

Use the function SHGetFolderPath. This function is preferred over querying environment variables since the latter can be modified to point to a wrong location. The documentation contains an example, which I repeat here (slightly adjusted):
使用函数SHGetFolderPath。此函数优于查询环境变量，因为后者可以修改为指向错误的位置。该文档包含一个示例，我在这里重复（略有调整）：
#include <Shlobj.h> // need to include definitions of constants
// .....
WCHAR path[MAX_PATH];
if (SUCCEEDED(SHGetFolderPathW(NULL, CSIDL_PROFILE, NULL, 0, path))) {
...
}

Just use the environment variables, in this particular case you want %HOMEPATH%and combine that with %SystemDrive%
只需使用环境变量，在这种特殊情况下，您需要%HOMEPATH%并将其与%SystemDrive%

Approach 1:
方法一：
#include <Shlobj.h>
std::string desktop_directory(bool path_w)
{
if (path_w == true)
{
WCHAR path[MAX_PATH + 1];
if (SHGetSpecialFolderPathW(HWND_DESKTOP, path, CSIDL_DESKTOPDIRECTORY, FALSE))
{
std::wstring ws(path);
std::string str(ws.begin(), ws.end());
return str;
}
else return NULL;
}
}
Approach 2:
方法二：
#include <Shlobj.h>
LPSTR desktop_directory()
{
static char path[MAX_PATH + 1];
if (SHGetSpecialFolderPathA(HWND_DESKTOP, path, CSIDL_DESKTOPDIRECTORY, FALSE)) return path;
else return NULL;
}
