# rio\_dev\_get(9)

Increments the reference count of the RIO device structure

## NAME

rio\_dev\_get - Increments the reference count of the RIO device structure

## SYNOPSIS

**struct rio\_dev \* rio\_dev\_get(struct rio\_dev \*** *rdev***);**

## ARGUMENTS

*rdev*

## DESCRIPTION

Each live reference to a device should be refcounted.
