Class VkSemaphoreGetFdInfoKHR

  • All Implemented Interfaces:
    java.lang.AutoCloseable, org.lwjgl.system.NativeResource, org.lwjgl.system.Pointer
    public class VkSemaphoreGetFdInfoKHR
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
    Structure describing a POSIX FD semaphore export operation.
    Description

    The properties of the file descriptor returned depend on the value of handleType. See VkExternalSemaphoreHandleTypeFlagBits for a description of the properties of the defined external semaphore handle types.

    Valid Usage
    • handleType must have been included in VkExportSemaphoreCreateInfo::handleTypes when semaphore’s current payload was created
    • semaphore must not currently have its payload replaced by an imported payload as described below in Importing Semaphore Payloads unless that imported payload’s handle type was included in VkExternalSemaphoreProperties::exportFromImportedHandleTypes for handleType
    • If handleType refers to a handle type with copy payload transference semantics, as defined below in Importing Semaphore Payloads, there must be no queue waiting on semaphore
    • If handleType refers to a handle type with copy payload transference semantics, semaphore must be signaled, or have an associated semaphore signal operation pending execution
    • handleType must be defined as a POSIX file descriptor handle
    • If handleType refers to a handle type with copy payload transference semantics, semaphore must have been created with a VkSemaphoreType of SEMAPHORE_TYPE_BINARY
    • If handleType refers to a handle type with copy payload transference semantics, semaphore must have an associated semaphore signal operation that has been submitted for execution and any semaphore signal operations on which it depends (if any) must have also been submitted for execution

        public VkSemaphoreGetFdInfoKHR​(java.nio.ByteBuffer container)
        Creates a VkSemaphoreGetFdInfoKHR 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.
