          unsigned int OldSize;
          unsigned int NewSize;

PARAMETERS

       OldSize             Old size of the memory block.

       NewSize             New size of the memory block.

               char ∗ s;
            {
               t = (char ∗)autresizeblock( t, strlen(t)+1, strlen(t)+strlen(s)+1);
               strcat(t, s);
               return t;
            }
