public class VkSemaphoreGetWin32HandleInfoKHR extends org.lwjgl.system.Struct<VkSemaphoreGetWin32HandleInfoKHR> 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
