# addlores(3)

create a logical resistor

## NAME

addlores - create a logical resistor

## SYNOPSYS

```
#include "mlo.h"
lores_list ∗addlores(ptfig,type,resi,rcon1,rcon2,name)
lofig_list ∗ptfig ;
char type ;
double resi ;
losig_list ∗rcon1, ∗rcon2 ;
const char ∗name ;
```

## PARAMETERS

- *ptfig*

  Pointer to the figure in which the resistor should be added

- *type*

  Resistor type

- *resi*

  Resistor value in Ohms

- *rcon1*

  Pointer to the signal to be connected on the resistor top plate

- *rcon2*

  Pointer to the signal to be connected on the resistor bottom plate

- *name*

  Resistor instance name

## DESCRIPTION

**addlores** creates a new resistor, and adds it to the list of resistors pointed to by *ptfig -\> LORES*. The new resistor is  added in front of the list, and becomes itself the list head.\
 The *type* parameter can take one value :

- **RESMIM**

  for a metal resistor

The *resi* argument is the resistor value in Ohms.\
 Two connectors are created each time a resistor is added, and the *rcon1* and *rcon2* **losigs** are attached to the *SIG* field of the **locon** of the appropriate connector. The connectors names are *rcon1*  and *rcon2*; their direction, *DIR*, are set to **'R'**, and their *TYPE* **INTERNAL**. For details on the structures, see [**locon**(3)](/locon/3.md) and [**lores**(3)](/lores/3.md).

## RETURN VALUE

**addlores** returns a pointer to the newly created resistor.

## ERRORS

**"∗∗∗ mbk error ∗∗∗ illegal resistor type :** *type***"**

The *type* is not a legal resistor type.

## EXAMPLE

```
#include "mlo.h"
void parallel_resistors(void) /∗ netlist of two parallel resistors ∗/
{
  lofig_list ∗pt  = NULL ;
  losig_list ∗in  = NULL ;
  losig_list ∗out = NULL ;
  pt = addlofig("parallel_resistors") ;
  addlocon(pt,"in",in = givelosig(pt,0),IN) ;
  addlocon(pt,"out",out = givelosig(pt,1),OUT) ;
  addlores(pt,RESMIM,0.2e-6,in,out,"res1") ;
  addlores(pt,RESMIM,0.2e-6,in,out,"res2") ;
}
```
