[C++] casting da char * a PWSTR *

[gianvituzzi]

solo una cosa, con questo codice ho un errore:

#include <iostream>
#include <cstdlib>
#include <tchar.h>
#include <shlobj.h>
#include <shlwapi.h>

int _tmain()
{
    TCHAR szPath[MAX_PATH] = {0};

    HRESULT res = SHGetFolderPath(NULL,
                                  CSIDL_LOCAL_APPDATA|CSIDL_FLAG_DONT_VERIFY,
                                  NULL,
                                  0,
                                  szPath);

    std::cout << szPath << std::endl;

    PathAppend(szPath, TEXT("myfile.txt"));

    std::cout << szPath << std::endl;

    system("pause");
    return EXIT_SUCCESS;
} 

main.obj : error LNK2019: unresolved external symbol __imp__PathAppendA@8 referenced in function _main
