# sortlocon(3)

sort the logical connectors of a figure by name

## NAME

sortlocon - sort the logical connectors of a figure by name

## SYNOPSYS

```
#include "mlo.h"
void sortlocon(connectors)
locon_list ∗∗connectors;
```

## PARAMETERS

- *connectors*

  Pointer to the head of the connector list that is to be sorted

## DESCRIPTION

**sortlocon** sorts the list of logical connectors pointed to by *∗connectors*. The connectors are sorted by names, using a numerical comparison function that ensures **x\_12 \> x\_2**.\
 The standart [**qsort**(3)](/qsort/3.md) function library is called for sorting. Therefore, a table the number of connectors wide is created. This is not very memory consuming since the number of connectors in a circuit interface is quite small, nor very time consuming since this algorithm runs in a n log n time.

## EXAMPLE

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