Class EXTBufferDeviceAddress

java.lang.Object

org.lwjgl.vulkan.EXTBufferDeviceAddress

public class EXTBufferDeviceAddress
extends java.lang.Object

This extension allows the application to query a 64-bit buffer device address value for a buffer, which can be used to access the buffer memory via the PhysicalStorageBufferEXT storage class in the GL_EXT_buffer_reference GLSL extension and SPV_EXT_physical_storage_buffer SPIR-V extension.

It also allows buffer device addresses to be provided by a trace replay tool, so that it matches the address used when the trace was captured.

Method Detail

nvkGetBufferDeviceAddressEXT

public static long nvkGetBufferDeviceAddressEXT(org.lwjgl.vulkan.VkDevice device,
                                                long pInfo)

Unsafe version of: GetBufferDeviceAddressEXT

vkGetBufferDeviceAddressEXT

public static long vkGetBufferDeviceAddressEXT(org.lwjgl.vulkan.VkDevice device,
                                               VkBufferDeviceAddressInfo pInfo)

See GetBufferDeviceAddress.

Parameters:

device - the logical device that the buffer was created on.

pInfo - a pointer to a VkBufferDeviceAddressInfo structure specifying the buffer to retrieve an address for.
