Equivalent of the GetTempPath on Windows Phone

Question

I am compiling a third party library libkml for Windows Universal App. And I notice that the following Win32 API is not available on anything but WINAPI_PARTITION_DESKTOP.

The following is from fileapi.h:

#if WINAPI_FAMILY_PARTITION(WINAPI_PARTITION_DESKTOP)

WINBASEAPI
DWORD
WINAPI
GetTempPathW(
    _In_ DWORD nBufferLength,
    _Out_writes_to_opt_(nBufferLength, return + 1) LPWSTR lpBuffer
    );
... 
#endif

Does anyone know the equivalent function for this GetTempPath for Windows Store App and Windows Phone App?

Answer 1

Here is an example GetTemporaryDirectory() wrapper function taken from the following MSDN blog article about "Writing shared code for Windows Store and Win32 desktop apps":

Dual-use Coding Techniques for Games, part 3.

void GetTemporaryDirectory( wchar_t* dir, size_t maxsize )
{
    if ( !maxsize ) return;
    *dir = 0;
    #if !defined(WINAPI_FAMILY) || (WINAPI_FAMILY == WINAPI_FAMILY_DESKTOP_APP)
    DWORD nChars = GetTempPath( maxsize, dir );
    if ( nChars > 0 )
        dir[nChars-1] = '\0'; // Trim trialing '\'
    else
        *dir = 0;
    #else // Windows Store WinRT app
    auto folder = Windows::Storage::ApplicationData::Current->TemporaryFolder;
    wcscpy_s( dir, maxsize, folder->Path->Data() );
    #endif // WINAPI_FAMILY_PARTITION
}
