Class VkSemaphoreGetWin32HandleInfoKHR

  • All Implemented Interfaces:
    java.lang.AutoCloseable, org.lwjgl.system.NativeResource, org.lwjgl.system.Pointer
    public class VkSemaphoreGetWin32HandleInfoKHR
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
    Structure describing a Win32 handle semaphore export operation.
    Description

    The properties of the handle 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 the semaphore’s current payload was created
    • If handleType is defined as an NT handle, GetSemaphoreWin32HandleKHR must be called no more than once for each valid unique combination of semaphore and handleType
    • 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 an NT handle or a global share handle
