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);
