C Specification

A descriptor pool maintains a pool of descriptors, from which descriptor sets are allocated. Descriptor pools are externally synchronized, meaning that the application must not allocate and/or free descriptor sets from the same pool in multiple threads simultaneously.

Descriptor pools cannot be destroyed https://registry.khronos.org/vulkansc/specs/1.0-extensions/html/vkspec.html#SCID-4.

If VkPhysicalDeviceVulkanSC10Properties::deviceDestroyFreesMemory is VK_TRUE, the memory is returned to the system when the device is destroyed. Otherwise, it may not be returned to the system until the process is terminated.

Descriptor pools are represented by VkDescriptorPool handles:

// Provided by VK_VERSION_1_0
VK_DEFINE_NON_DISPATCHABLE_HANDLE(VkDescriptorPool)
