# udev\_list\_entry(3)

Iterate and access udev lists

## NAME

udev\_list\_entry, udev\_list\_entry\_get\_next, udev\_list\_entry\_get\_by\_name, udev\_list\_entry\_get\_name, udev\_list\_entry\_get\_value - Iterate and access udev lists

## SYNOPSIS

```
#include <libudev.h>
```

**struct udev\_list\_entry \*udev\_list\_entry\_get\_next(struct udev\_list\_entry \****list\_entry***);**

**struct udev\_list\_entry \*udev\_list\_entry\_get\_by\_name(struct udev\_list\_entry \****list\_entry***, const char \****name***);**

**const char \*udev\_list\_entry\_get\_name(struct udev\_list\_entry \****list\_entry***);**

**const char \*udev\_list\_entry\_get\_value(struct udev\_list\_entry \****list\_entry***);**

## RETURN VALUE

On success, **udev\_list\_entry\_get\_next()** and **udev\_list\_entry\_get\_by\_name()** return a pointer to the requested list entry. If no such entry can be found, or on failure, **NULL** is returned.

On success, **udev\_list\_entry\_get\_name()** and **udev\_list\_entry\_get\_value()** return a pointer to a constant string representing the requested value. The string is bound to the lifetime of the list entry itself. On failure, **NULL** is returned.

## HISTORY

**udev\_list\_entry\_get\_next()**, **udev\_list\_entry\_get\_by\_name()**, **udev\_list\_entry\_get\_name()**, and **udev\_list\_entry\_get\_value()** were added in version 221.
