## Description

This extension provides versions of vkBindBufferMemory and vkBindImageMemory that allow multiple bindings to be performed at once, and are extensible.

This extension also introduces `VK_IMAGE_CREATE_ALIAS_BIT_KHR`, which allows “identical” images that alias the same memory to interpret the contents consistently, even across image layout changes.

## Promotion to Vulkan 1.1

All functionality in this extension is included in core Vulkan 1.1, with the KHR suffix omitted. The original type, enum, and command names are still available as aliases of the core functionality.

## New Commands

- vkBindBufferMemory2KHR

- vkBindImageMemory2KHR

## New Structures

- VkBindBufferMemoryInfoKHR

- VkBindImageMemoryInfoKHR

## New Enum Constants

- `VK_KHR_BIND_MEMORY_2_EXTENSION_NAME`

- `VK_KHR_BIND_MEMORY_2_SPEC_VERSION`

- Extending VkImageCreateFlagBits:

  - `VK_IMAGE_CREATE_ALIAS_BIT_KHR`

- Extending VkStructureType:

  - `VK_STRUCTURE_TYPE_BIND_BUFFER_MEMORY_INFO_KHR`

  - `VK_STRUCTURE_TYPE_BIND_IMAGE_MEMORY_INFO_KHR`

## Version History

- Revision 1, 2017-05-19 (Tobias Hector)

  - Pulled bind memory functions into their own extension
