C Specification

To destroy a micromap, call:

// Provided by VK_EXT_opacity_micromap
void vkDestroyMicromapEXT(
    VkDevice                                    device,
    VkMicromapEXT                               micromap,
    const VkAllocationCallbacks*                pAllocator);


  • device is the logical device that destroys the micromap.

  • micromap is the micromap to destroy.

  • pAllocator controls host memory allocation as described in the Memory Allocation chapter.


Valid Usage
  • VUID-vkDestroyMicromapEXT-micromap-07441
    All submitted commands that refer to micromap must have completed execution

  • VUID-vkDestroyMicromapEXT-micromap-07442
    If VkAllocationCallbacks were provided when micromap was created, a compatible set of callbacks must be provided here

  • VUID-vkDestroyMicromapEXT-micromap-07443
    If no VkAllocationCallbacks were provided when micromap was created, pAllocator must be NULL

Valid Usage (Implicit)
  • VUID-vkDestroyMicromapEXT-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkDestroyMicromapEXT-micromap-parameter
    If micromap is not VK_NULL_HANDLE, micromap must be a valid VkMicromapEXT handle

  • VUID-vkDestroyMicromapEXT-pAllocator-parameter
    If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure

  • VUID-vkDestroyMicromapEXT-micromap-parent
    If micromap is a valid handle, it must have been created, allocated, or retrieved from device

Host Synchronization
  • Host access to micromap must be externally synchronized
