## Name

VkMemoryHostPointerPropertiesEXT - Properties of external memory host pointer

Loading… please wait.

## C Specification

The `VkMemoryHostPointerPropertiesEXT` structure is defined as:

    // Provided by VK_EXT_external_memory_host
    typedef struct VkMemoryHostPointerPropertiesEXT {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           memoryTypeBits;
    } VkMemoryHostPointerPropertiesEXT;

## Members

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `memoryTypeBits` is a bitmask containing one bit set for every memory type which the specified host pointer can be imported as.

## Description

The value returned by `memoryTypeBits` must only include bits that identify memory types which are host visible.

Valid Usage (Implicit)

- VUID-VkMemoryHostPointerPropertiesEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_MEMORY_HOST_POINTER_PROPERTIES_EXT`

- VUID-VkMemoryHostPointerPropertiesEXT-pNext-pNext
  `pNext` must be `NULL`
