C Specification

The VkReleaseSwapchainImagesInfoEXT structure is defined as:

// Provided by VK_EXT_swapchain_maintenance1
typedef struct VkReleaseSwapchainImagesInfoEXT {
    VkStructureType    sType;
    const void*        pNext;
    VkSwapchainKHR     swapchain;
    uint32_t           imageIndexCount;
    const uint32_t*    pImageIndices;
} VkReleaseSwapchainImagesInfoEXT;


  • sType is a VkStructureType value identifying this structure.

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

  • swapchain is a swapchain to which images are being released.

  • imageIndexCount is the number of image indices to be released.

  • pImageIndices is a pointer to an array of indices into the array of swapchain’s presentable images, with imageIndexCount entries.


Valid Usage
  • VUID-VkReleaseSwapchainImagesInfoEXT-pImageIndices-07785
    Each element of pImageIndices must be the index of a presentable image acquired from the swapchain specified by swapchain

  • VUID-VkReleaseSwapchainImagesInfoEXT-pImageIndices-07786
    All uses of presentable images identified by elements of pImageIndices must have completed execution

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

  • VUID-VkReleaseSwapchainImagesInfoEXT-pNext-pNext
    pNext must be NULL

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

  • VUID-VkReleaseSwapchainImagesInfoEXT-pImageIndices-parameter
    pImageIndices must be a valid pointer to an array of imageIndexCount uint32_t values

  • VUID-VkReleaseSwapchainImagesInfoEXT-imageIndexCount-arraylength
    imageIndexCount must be greater than 0

Host Synchronization
  • Host access to swapchain must be externally synchronized
