# viewphref(3)

display elements of a phref\_list

## NAME

viewphref - display elements of a **phref\_list**

## SYNOPSYS

```
#include "mph.h"
void viewphref(pt)
phref_list ∗pt;
```

## PARAMETER

- *pt*

  Pointer to the **phref** to be scaned

## DESCRIPTION

**viewphref** scans all the primary elements of the **phref\_list**  pointed to by *pt*, and displays a textual output of the data strcuture contents.\
 Its use is mostly for debugging purposes, and educational ones, since the output is quite verbose, even if very easy to understand.

## EXAMPLE

```
#include <stdio.h>
#include "mph.h"
void view_ref(ptfig)
phfig_list ∗ptfig;
{
phref_list ∗ref;
	for (ref = ptfig->PHREF; ref; ref = ref->NEXT)
		viewphref(ref);
}
```
