Class VkImportMemoryFdInfoKHR

  • All Implemented Interfaces:
    java.lang.AutoCloseable, org.lwjgl.system.NativeResource, org.lwjgl.system.Pointer
    public class VkImportMemoryFdInfoKHR
extends org.lwjgl.system.Struct
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.

        public VkImportMemoryFdInfoKHR​(java.nio.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.
