C Specification

To export device memory as a Zircon handle that can be used by another instance, device, or process, the handle to the VkDeviceMemory must be retrieved using vkGetMemoryZirconHandleFUCHSIA:

// Provided by VK_FUCHSIA_external_memory
VkResult vkGetMemoryZirconHandleFUCHSIA(
    VkDevice                                    device,
    const VkMemoryGetZirconHandleInfoFUCHSIA*   pGetZirconHandleInfo,
    zx_handle_t*                                pZirconHandle);



Valid Usage (Implicit)
  • VUID-vkGetMemoryZirconHandleFUCHSIA-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkGetMemoryZirconHandleFUCHSIA-pGetZirconHandleInfo-parameter
    pGetZirconHandleInfo must be a valid pointer to a valid VkMemoryGetZirconHandleInfoFUCHSIA structure

  • VUID-vkGetMemoryZirconHandleFUCHSIA-pZirconHandle-parameter
    pZirconHandle must be a valid pointer to a zx_handle_t value
