---

The Input provides functions for setting input device event.

Required Header

#include <hal-device-input.h>

Overview

The Input provides the way to enable/disable input events from kernel.

The Input functions provide input control including:

• Load/Unload for input hal-backend module
• Disable/Enable input events from kernel

For more information on the Input features and the macros, see HAL Input programming guides and tutorials.
