public class VkD3D12FenceSubmitInfoKHR extends org.lwjgl.system.Struct<VkD3D12FenceSubmitInfoKHR> implements org.lwjgl.system.NativeResource
Structure specifying values for Direct3D 12 fence-backed semaphores.
Description

If the semaphore in VkSubmitInfo::pWaitSemaphores or VkSubmitInfo::pSignalSemaphores corresponding to an entry in pWaitSemaphoreValues or pSignalSemaphoreValues respectively does not currently have a payload referring to a Direct3D 12 fence, the implementation must ignore the value in the pWaitSemaphoreValues or pSignalSemaphoreValues entry.

Note

As the introduction of the external semaphore handle type EXTERNAL_SEMAPHORE_HANDLE_TYPE_D3D12_FENCE_BIT predates that of timeline semaphores, support for importing semaphore payloads from external handles of that type into semaphores created (implicitly or explicitly) with a VkSemaphoreType of SEMAPHORE_TYPE_BINARY is preserved for backwards compatibility. However, applications should prefer importing such handle types into semaphores created with a VkSemaphoreType of SEMAPHORE_TYPE_TIMELINE, and use the VkTimelineSemaphoreSubmitInfo structure instead of the VkD3D12FenceSubmitInfoKHR structure to specify the values to use when waiting for and signaling such semaphores.

Valid Usage
  • waitSemaphoreValuesCount must be the same value as VkSubmitInfo::waitSemaphoreCount, where this structure is in the pNext chain of a VkSubmitInfo structure
  • signalSemaphoreValuesCount must be the same value as VkSubmitInfo::signalSemaphoreCount, where this structure is in the pNext chain of a VkSubmitInfo structure
Valid Usage (Implicit)
  • sType must be STRUCTURE_TYPE_D3D12_FENCE_SUBMIT_INFO_KHR
  • If waitSemaphoreValuesCount is not 0, and pWaitSemaphoreValues is not NULL, pWaitSemaphoreValues must be a valid pointer to an array of waitSemaphoreValuesCount uint64_t values
  • If signalSemaphoreValuesCount is not 0, and pSignalSemaphoreValues is not NULL, pSignalSemaphoreValues must be a valid pointer to an array of signalSemaphoreValuesCount uint64_t values

    • VkD3D12FenceSubmitInfoKHR

      public VkD3D12FenceSubmitInfoKHR(ByteBuffer container)
      Creates a VkD3D12FenceSubmitInfoKHR 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.
