# dellotrs(3)

delete a logical transistor

## NAME

dellotrs - delete a logical transistor

## SYNOPSYS

```
#include "mlo.h"
int dellotrs(ptfig, pttrs)
lofig_list ∗ptfig;
lotrs_list ∗pttrs;
```

## PARAMETERS

- *ptfig*

  Pointer to the figure in which the transistor should be deleted

- *pttrs*

  Pointer to the transistor to be deleted.

## DESCRIPTION

**dellotrs** delete the transistor pointed to by *pttrs* in the figure  pointed to by *ptfig*.  The list consistency is maintainded, and the space freed. The transistor connectors are also freed, since if the transistor disapear, no more connections can occur on it.

## RETURN VALUE

**dellotrs** returns **1** if the transistor has been deleted, **0** if the transistor pointer does nit exists in the list.

## EXAMPLE

```
#include "mlo.h"
char ∗was_existing(ptfig, pttrs)
lofig_list ∗ptfig;
lotrs_list ∗pttrs;
{
   return dellotrs(ptfig, pttrs) ? "you just killed it!"
                                 : "wasn't here anyway";
}
```
