WriteFile(...) exception

[bkelly]

Windows XP Pro, Visual Studio 2008, MFC application.
When I call

WriteFile( m_log_file_handle, &m_log_message, m_write_length, mp_bytes_written,
                NULL );

I wind up in the debugger about 13 levels deep and do not understand what it is trying to tell me.

My solution is:

try{
  WriteFile( ... );
  }
catch
  {
   // need help here
}

I don't know what can be thrown and my Visual Studio help for WriteFile says nothing about exceptions. What can I put in the catch section to give me a clue as to what it does not like about my WriteFile call.
