public Class QCOMEXTHostPtr

extends Object
Class Inheritance
Imports
javax.annotation.*, java.nio.*, org.lwjgl.*, org.lwjgl.system.*
Native bindings to the qcom_ext_host_ptr extension.

This extension extends the functionality provided by CreateBuffer, CreateImage2D, CreateImage3D. It allows applications to specify a new flag MEM_EXT_HOST_PTR_QCOM which enables the driver to map external memory allocations --to be defined in future layered extensions-- to the device's address space and thus avoiding having to copy data back and forth between the host and the device.

Requires CL11.
