Yes, but to use memcpy, you need the length. This can be calculated by a
variation of Lars code: untested


static int zerolength( PSZ pszzString)
{
         PSZ            p = pszzString;

   if (p != NULL)
      {
      while ((*p != 0) || (*(p+1) != 0)) // !a || !b == !(a && b)
         {

         p++;


         }
         return (p +1 - pszzString); // calculate length
      }
   else
      {
          return 0; // length is zero
      }
}

Now you can use the returned length for malloc and memcpy.

CU/2
