C Specification
Bits which can be set in VkDescriptorPoolCreateInfo::flags
to
enable operations on a descriptor pool are:
typedef enum VkDescriptorPoolCreateFlagBits {
VK_DESCRIPTOR_POOL_CREATE_FREE_DESCRIPTOR_SET_BIT = 0x00000001,
VK_DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BIT_EXT = 0x00000002,
VK_DESCRIPTOR_POOL_CREATE_FLAG_BITS_MAX_ENUM = 0x7FFFFFFF
} VkDescriptorPoolCreateFlagBits;
Description
-
VK_DESCRIPTOR_POOL_CREATE_FREE_DESCRIPTOR_SET_BIT
specifies that descriptor sets can return their individual allocations to the pool, i.e. all of vkAllocateDescriptorSets, vkFreeDescriptorSets, and vkResetDescriptorPool are allowed. Otherwise, descriptor sets allocated from the pool must not be individually freed back to the pool, i.e. only vkAllocateDescriptorSets and vkResetDescriptorPool are allowed. -
VK_DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BIT_EXT
specifies that descriptor sets allocated from this pool can include bindings with theVK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT_EXT
bit set. It is valid to allocate descriptor sets that have bindings that do not set theVK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT_EXT
bit from a pool that hasVK_DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BIT_EXT
set.
