Class VkImportMemoryFdInfoKHR

  • All Implemented Interfaces:
    java.lang.AutoCloseable, NativeResource, Pointer

    public class VkImportMemoryFdInfoKHR
    extends Struct
    implements NativeResource
    import memory created on the same physical device from a file descriptor.

    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.

    Applications can import the same underlying memory 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.
