vkGetMemoryZirconHandlePropertiesFUCHSIA(3)

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);

Parameters

device is the VkDevice.
handleType is a VkExternalMemoryHandleTypeFlagBits value specifying the type of zirconHandle
zirconHandle is a zx_handle_t (Zircon) handle to the external resource.
pMemoryZirconHandleProperties is a pointer to a VkMemoryZirconHandlePropertiesFUCHSIA structure in which the result will be stored.
