C Specification
To import memory from a Metal handle, add a
VkImportMemoryMetalHandleInfoEXT structure to the pNext chain of
the VkMemoryAllocateInfo structure.
The VkImportMemoryMetalHandleInfoEXT structure is defined as:
// Provided by VK_EXT_external_memory_metal
typedef struct VkImportMemoryMetalHandleInfoEXT {
VkStructureType sType;
const void* pNext;
VkExternalMemoryHandleTypeFlagBits handleType;
void* handle;
} VkImportMemoryMetalHandleInfoEXT;
Members
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
handleTypeis a VkExternalMemoryHandleTypeFlagBits value specifying the type ofhandleorname. -
handleisNULLor the external handle to import.
Description
Importing memory object payloads from Metal handles shares the ownership of the handle to the Vulkan implementation.
Applications can import the same payload into multiple instances of Vulkan,
into the same instance from which it was exported, and multiple times into a
given Vulkan instance.
In all cases, each import operation must create a distinct
VkDeviceMemory object.
