C Specification

If the pNext chain of VkBindImageMemoryInfo includes a VkBindImageMemorySwapchainInfoKHR structure, then that structure includes a swapchain handle and image index indicating that the image will be bound to memory from that swapchain.

The VkBindImageMemorySwapchainInfoKHR structure is defined as:

// Provided by VK_KHR_swapchain with VK_VERSION_1_1, VK_KHR_device_group with VK_KHR_swapchain
typedef struct VkBindImageMemorySwapchainInfoKHR {
    VkStructureType    sType;
    const void*        pNext;
    VkSwapchainKHR     swapchain;
    uint32_t           imageIndex;
} VkBindImageMemorySwapchainInfoKHR;


  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • swapchain is VK_NULL_HANDLE or a swapchain handle.

  • imageIndex is an image index within swapchain.


If swapchain is not NULL, the swapchain and imageIndex are used to determine the memory that the image is bound to, instead of memory and memoryOffset.

Memory can be bound to a swapchain and use the pDeviceIndices or pSplitInstanceBindRegions members of VkBindImageMemoryDeviceGroupInfo.

Valid Usage
  • VUID-VkBindImageMemorySwapchainInfoKHR-imageIndex-01644
    imageIndex must be less than the number of images in swapchain

Valid Usage (Implicit)
  • VUID-VkBindImageMemorySwapchainInfoKHR-sType-sType

  • VUID-VkBindImageMemorySwapchainInfoKHR-swapchain-parameter
    swapchain must be a valid VkSwapchainKHR handle

Host Synchronization
  • Host access to swapchain must be externally synchronized
