C++: GetTempPath() without tilde (~)

I need to get temp path. So I tried GetTempPath() and std::getenv("TEMP"). The problem is that the result contains ~ symbol, for example C:\Users\OLEKSI~1.ALE\AppData\Local\Temp.
Is it possible to get full temp path like C:\Users\Oleksii\AppData\Local\Temp?

>Solution :

GetLongPathName function:

Converts the specified path to its long form.

DWORD GetLongPathNameW(
  [in]  LPCWSTR lpszShortPath,
  [out] LPWSTR  lpszLongPath,
  [in]  DWORD   cchBuffer
);

DWORD GetLongPathNameA(
  [in]  LPCSTR lpszShortPath,
  [out] LPSTR  lpszLongPath,
  [in]  DWORD  cchBuffer
);

Set lpszShortPath = short path with ~ symbols. Read result from lpszLongPath.
