C Specification

To obtain the memoryTypeIndex for the VkMemoryAllocateInfo structure, call vkGetMemoryZirconHandlePropertiesFUCHSIA:

// Provided by VK_FUCHSIA_external_memory
VkResult vkGetMemoryZirconHandlePropertiesFUCHSIA(
    VkDevice                                    device,
    VkExternalMemoryHandleTypeFlagBits          handleType,
    zx_handle_t                                 zirconHandle,
    VkMemoryZirconHandlePropertiesFUCHSIA*      pMemoryZirconHandleProperties);
