org.lwjgl.vulkan.KHRMapMemory2

public class KHRMapMemory2
extends Object

This extension provides extensible versions of the Vulkan memory map and unmap commands. The new commands are functionally identical to the core commands, except that their parameters are specified using extensible structures that can be used to pass extension-specific information.

Promotion to Vulkan 1.4

Functionality in this extension is included in core Vulkan 1.4 with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.

Method Details

nvkMapMemory2KHR

public static int nvkMapMemory2KHR(org.lwjgl.vulkan.VkDevice device,
 long pMemoryMapInfo,
 long ppData)

Unsafe version of: MapMemory2KHR

vkMapMemory2KHR

public static int vkMapMemory2KHR(org.lwjgl.vulkan.VkDevice device,
 VkMemoryMapInfo pMemoryMapInfo,
 org.lwjgl.PointerBuffer ppData)

See MapMemory2.

Parameters:

device - the logical device that owns the memory.

pMemoryMapInfo - a pointer to a VkMemoryMapInfo structure describing parameters of the map.

ppData - a pointer to a void * variable in which is returned a host-accessible pointer to the beginning of the mapped range. This pointer minus VkMemoryMapInfo::offset must be aligned to at least VkPhysicalDeviceLimits::minMemoryMapAlignment.

nvkUnmapMemory2KHR

public static int nvkUnmapMemory2KHR(org.lwjgl.vulkan.VkDevice device,
 long pMemoryUnmapInfo)

Unsafe version of: UnmapMemory2KHR

vkUnmapMemory2KHR

public static int vkUnmapMemory2KHR(org.lwjgl.vulkan.VkDevice device,
 VkMemoryUnmapInfo pMemoryUnmapInfo)

See UnmapMemory2.

Parameters:

device - the logical device that owns the memory.

pMemoryUnmapInfo - a pointer to a VkMemoryUnmapInfo structure describing parameters of the unmap.
