NAME

       sortlosig - sort the logical signals of a figure by name

SYNOPSYS

       #include "mlo.h"
       void sortlosig(signals)
       losig_list ∗∗signals;

PARAMETERS

       ∗∗signals           Pointer to the head of the list of signals that is to be sorted

DESCRIPTION

       sortlosig  sorts  the  list of signals pointed to by signals.  The signals are sorted by names, but since
       names are not the signals identifier, the getsigname(3) routine is called to retrieve a signal name.
       The standart qsort(3) function library is called for sorting.  Therefore, a table the  number  of  signal
       wide  is  created,  requiring  a lot of memory with big circuits.  Also, even if qsort(3) runs in n log n
       time, getsigname(3) is called twice, and the natural comparison function once, and  this  is  quite  time
       consuming with big circuits.  It is recommended to use this function only if needed.

EXAMPLE

       #include "mlo.h"
       void savesorted(figname)
       char ∗figname;
       {
       lofig_list ∗figure = getlosig(figname, 'A');
         sortlocon(&figure->LOCON);
         sortlosig(&figure->LOSIG);
         savelofig(figure);
       }
