vkGetSemaphoreZirconHandleFUCHSIA

To export a Zircon event handle representing the payload of a semaphore, call:

VkResult vkGetSemaphoreZirconHandleFUCHSIA(
    VkDevice device,
    const VkSemaphoreGetZirconHandleInfoFUCHSIA* pGetZirconHandleInfo,
    zx_handle_t* pZirconHandle);

• device is the logical device that created the semaphore being exported.
• pGetZirconHandleInfo is a pointer to a VkSemaphoreGetZirconHandleInfoFUCHSIA structure containing parameters of the export operation.
• pZirconHandle will return the Zircon event handle representing the semaphore payload.

Each call to vkGetSemaphoreZirconHandleFUCHSIA must create a Zircon event handle and transfer ownership of it to the application. To avoid leaking resources, the application must release ownership of the Zircon event handle when it is no longer needed.

Exporting a Zircon event handle from a semaphore may have side effects depending on the transference of the specified handle type, as described in Importing Semaphore State.
