Memory

---

The Memory provides functions for getting memory information.

Required Header

#include <hal-device-memory.h>

Overview

The Memory provides the way to get memory information.

The Memory functions provide memory information including:

• Load/Unload for memory hal-backend module
• Getter for gpu information
• Getter for GEM information

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