The Win32 Foundation Classes (WFC) are a library of C++ classes that extend Microsoft Foundation Classes (MFC) beyond mere GUI applications, and provide extensive support for system and NT specific applications

<H2>Declaration</H2>
<PRE><CODE>void wfc_convert_double_null_terminated_string( const BYTE * unicode_string, buffer, CStringArray&amp; string_array ) )</CODE></PRE>

<H2>Description</H2>
This function converts a double-NULL terminated string to a CStringArray object.

<H2>Example</H2>

<PRE><CODE>#include &lt;wfc.h&gt;

int _tmain( int number_of_command_line_arguments, LPCTSTR command_line_arguments[] )
{
   <A HREF="WfcTrace.htm">WFCTRACEINIT</A>( TEXT( &quot;_tmain()&quot; ) );

   TCHAR dos_device_names[ 4096 ];

   ZeroMemory( dos_device_names, sizeof( dos_device_names ) );

   DWORD return_value = 0;

   return_value = QueryDosDevice( NULL, dos_device_names, DIMENSION_OF( dos_device_names ) );

   CStringArray names;

   <B>wfc_convert_double_null_terminated_string</B>( reinterpret_cast&lt; const BYTE * &gt;( dos_device_names ), names );

   int loop_index         = 0;
   int number_of_elements = names.GetSize();

   while( loop_index < number_of_elements )
   {
      _tprintf( TEXT( &quot;%s\n&quot; ), (LPCTSTR) names.GetAt( loop_index ) );
      WFCTRACEVAL( TEXT( &quot;Name: &quot; ), names.GetAt( loop_index ) );
      loop_index++;
   }

   return( EXIT_SUCCESS );

I'm just a simple little NT programmer. Most of the work I do is remote controlling equipment in real time. I started out using Windows 3.0. Then came 3.1 and then NT. I started using NT but unfortunately, Microsoft didn't. I started using MFC but unfortunately, Microsoft didn't (and still doesn't) put any real support for NT into MFC so I wrote a bunch of C++ classes to make my life easier. Like all class libraries, mine grew. Now I'm giving it away, I call it Win32 Foundation Classes.
