public class VkImportMemoryFdInfoKHR extends org.lwjgl.system.Struct<VkImportMemoryFdInfoKHR> implements org.lwjgl.system.NativeResource
Import memory created on the same physical device from a file descriptor.
Description

Importing memory from a file descriptor transfers ownership of the file descriptor from the application to the Vulkan implementation. The application must not perform any operations on the file descriptor after a successful import. The imported memory object holds a reference to its payload.

Applications can import the same payload into multiple instances of Vulkan, into the same instance from which it was exported, and multiple times into a given Vulkan instance. In all cases, each import operation must create a distinct VkDeviceMemory object.

    • VkImportMemoryFdInfoKHR

      public VkImportMemoryFdInfoKHR(ByteBuffer container)
      Creates a VkImportMemoryFdInfoKHR instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

      The created instance holds a strong reference to the container object.
