To return all descriptor sets allocated from a given pool to the pool, rather than freeing individual descriptor sets, call:
// Provided by VK_VERSION_1_0 VkResult vkResetDescriptorPool( VkDevice device, VkDescriptorPool descriptorPool, VkDescriptorPoolResetFlags flags);
deviceis the logical device that owns the descriptor pool.
descriptorPoolis the descriptor pool to be reset.
flagsis reserved for future use.
Resetting a descriptor pool recycles all of the resources from all of the descriptor sets allocated from the descriptor pool back to the descriptor pool, and the descriptor sets are implicitly freed.
