How to get list of selected files when using GetOpenFileName() with multiselect flag?

Question

I have tried googling, but people seem to have the same problem: we can\'t get a list of the selected files.

This is a simple piece of working code that is similar t

Here is a more complete version of the answers by Niall and Remy.

vector &filePaths;

if ( GetOpenFileName( &ofn ) == TRUE )
{
    wchar_t *p = ofn.lpstrFile;
    wstring path = p;
    p += path.size() + 1;
    if ( *p == 0 )
    {
        // there is only one string, being the full path to the file
        filePaths.push_back( ConvertWideCharToUtf8( path.c_str() ) );
    }
    else
    {
        // multiple files follow the directory
        for ( ; *p != 0 ; )
        {
            wstring fileName = p;
            filePaths.push_back( ConvertWideCharToUtf8( ( path + L"\\" + fileName ).c_str() ) );
            p += fileName.size() + 1;
        }
    }
}

Where we also have the function:

string ConvertWideCharToUtf8( const wchar_t *wideText )
{
    int len = WideCharToMultiByte( CP_UTF8, 0, wideText, -1, NULL, 0, NULL, NULL );
    char *buffer = (char *)malloc( len );
    WideCharToMultiByte( CP_UTF8, 0, wideText, -1, buffer, len, NULL, NULL );
    string s = buffer;
    free( buffer );

    return s;
}
