# rlist\_nth(3)

get the nth entry in the list

## NAME

rlist\_nth - get the nth entry in the list

## SYNOPSIS

\#include \<roy.h\>

void \* rlist\_nth (RList \* *list*, unsigned int *nth*);

## DESCRIPTION

This call indexes into *list* as if it were an array of entries. Entry 1 is accessed with *nth* of 0, and the last entry is accessed with *nth* of last - 1.

## RETURN VALUE

The return type of *void \** is used so the compiler will upgrade the return value to your entry type. As long as the value isn't NULL the value should be compatable with an RListEntry pointer. See [*rlist*(3)](/rlist/3.md) on how to create RListEntry compatible entry structs.

This call returns the *nth* entry in *list* or NULL if *list* has *nth* or fewer entries.

## ERRORS

A call to [*rlist\_nth*(3)](/rlist_nth/3.md) will never fail, but will return NULL if *nth* is out of range.

## FUNCTION

The [*rlist\_nth*(3)](/rlist_nth/3.md) api is implemented using a function.
