vkDestroyDescriptorPool

To destroy a descriptor pool, call:

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

• 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.

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.
