VkImportMetalBufferInfoEXT

To import a Metal MTLBuffer object to underlie a VkDeviceMemory object, include a VkImportMetalBufferInfoEXT structure in the pNext chain of the VkMemoryAllocateInfo structure in a vkAllocateMemory command.

The VkImportMetalBufferInfoEXT structure is defined as:

typedef struct VkImportMetalBufferInfoEXT {
    VkStructureType sType;
    const void* pNext;
    MTLBuffer_id mtlBuffer;
} VkImportMetalBufferInfoEXT;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• mtlBuffer is the Metal id<MTLBuffer> object that is to underlie the VkDeviceMemory.

The application must ensure that the configuration of the id<MTLBuffer> object is compatible with the configuration of the VkDeviceMemory. Failure to do so results in undefined: behavior.
