C Specification

To destroy a descriptor pool, call:

void vkDestroyDescriptorPool(
    VkDevice                                    device,
    VkDescriptorPool                            descriptorPool,
    const VkAllocationCallbacks*                pAllocator);

Parameters

  • device is the logical device that destroys the descriptor pool.

  • descriptorPool is the descriptor pool to destroy.

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

Description

When a pool is destroyed, all descriptor sets allocated from the pool are implicitly freed and become invalid. Descriptor sets allocated from a given pool do not need to be freed before destroying that descriptor pool.

Valid Usage
  • All submitted commands that refer to descriptorPool (via any allocated descriptor sets) must have completed execution

  • If VkAllocationCallbacks were provided when descriptorPool was created, a compatible set of callbacks must be provided here

  • If no VkAllocationCallbacks were provided when descriptorPool was created, pAllocator must be NULL

Valid Usage (Implicit)
  • device must be a valid VkDevice handle

  • If descriptorPool is not VK_NULL_HANDLE, descriptorPool must be a valid VkDescriptorPool handle

  • If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure

  • If descriptorPool is a valid handle, it must have been created, allocated, or retrieved from device

Host Synchronization
  • Host access to descriptorPool must be externally synchronized
