NAME

       guessextdir - guess external connectors directions from internal connectors directions

SYNOPSYS

       #include "mlo.h"
       int guessextdir(ptfig)
       lofig_list ∗ptfig;

PARAMETER

       ptfig               Pointer to a lofig_list

DESCRIPTION

       The  guessextdir function guesses external connectors directions from internal connectors'

EXAMPLE

       #include "mut.h"
       #include "mlo.h"
       lofig_list ∗ getgoodlofig(figname, mode)
       char ∗figname;
       char mode;
       {
       lofig_list ∗ptfig;
          ptfig = getlofig(figname, mode);
          restorealldir(ptfig);
          guessextdir(ptfig);
          return ptfig;
       }
