VkImportMetalBufferInfoEXT(3)

Name

VkImportMetalBufferInfoEXT - Structure that identifies a Metal MTLBuffer object to use when creating a VkDeviceMemory object.

C Specification

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:

// Provided by VK_EXT_metal_objects
typedef struct VkImportMetalBufferInfoEXT {
    VkStructureType    sType;
    const void*        pNext;
    MTLBuffer_id       mtlBuffer;
} VkImportMetalBufferInfoEXT;

Members

  • 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.

Description

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.

Valid Usage (Implicit)

  • VUID-VkImportMetalBufferInfoEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_IMPORT_METAL_BUFFER_INFO_EXT
