如何在C中获取UWP应用的安装位置？

#include <Windows.h>
#include <Shlobj.h>

wchar_t* GetUWPAppInstallLocation()
{
    wchar_t* installLocation = NULL;
    PWSTR localAppData;
    HRESULT hr = SHGetKnownFolderPath(FOLDERID_LocalAppData, 0, NULL, &localAppData);
    if (SUCCEEDED(hr))
    {
        wchar_t packageFullName[MAX_PATH];
        UINT32 packageFullNameLength = MAX_PATH;
        hr = GetCurrentPackageFullName(&packageFullNameLength, packageFullName);
        if (SUCCEEDED(hr))
        {
            wchar_t* packageNameStart = wcschr(packageFullName, L'=');
            if (packageNameStart != NULL)
            {
                packageNameStart++;
                wchar_t* packageNameEnd = wcschr(packageNameStart, L'_');
                if (packageNameEnd != NULL)
                {
                    *packageNameEnd = L'\0';
                    size_t installLocationLength = wcslen(localAppData) + wcslen(packageNameStart) + 2;
                    installLocation = (wchar_t*)malloc(installLocationLength * sizeof(wchar_t));
                    if (installLocation != NULL)
                    {
                        swprintf_s(installLocation, installLocationLength, L"%s\\Packages\\%s", localAppData, packageNameStart);
                    }
                }
            }
        }
        CoTaskMemFree(localAppData);
    }
    return installLocation;
}
