| pattern DESCRIPTOR_POOL_CREATE_FREE_DESCRIPTOR_SET_BIT :: DescriptorPoolCreateFlagBits | DESCRIPTOR_POOL_CREATE_FREE_DESCRIPTOR_SET_BIT specifies that
descriptor sets can return their individual allocations to the pool,
i.e. all of allocateDescriptorSets,
freeDescriptorSets, and
resetDescriptorPool are allowed.
Otherwise, descriptor sets allocated from the pool must not be
individually freed back to the pool, i.e. only
allocateDescriptorSets and
resetDescriptorPool are allowed.
|
| pattern DESCRIPTOR_POOL_CREATE_ALLOW_OVERALLOCATION_POOLS_BIT_NV :: DescriptorPoolCreateFlagBits | DESCRIPTOR_POOL_CREATE_ALLOW_OVERALLOCATION_POOLS_BIT_NV specifies
that the implementation should allow the application to allocate more
descriptors from the pool than was specified by the
DescriptorPoolSize::descriptorCount for
any descriptor type as specified by
DescriptorPoolCreateInfo::poolSizeCount
and
DescriptorPoolCreateInfo::pPoolSizes, as
available resources allow. The implementation may use the
descriptorCount for each descriptor type to allocate the initial pool,
but the application is allowed to set the poolSizeCount to zero, or
any of the descriptorCount values in the pPoolSizes array to zero.
|
| pattern DESCRIPTOR_POOL_CREATE_ALLOW_OVERALLOCATION_SETS_BIT_NV :: DescriptorPoolCreateFlagBits | DESCRIPTOR_POOL_CREATE_ALLOW_OVERALLOCATION_SETS_BIT_NV specifies that
the implementation should allow the application to allocate more than
DescriptorPoolCreateInfo::maxSets
descriptor set objects from the descriptor pool as available resources
allow. The implementation may use the maxSets value to allocate the
initial available sets, but using zero is permitted.
|
| pattern DESCRIPTOR_POOL_CREATE_HOST_ONLY_BIT_EXT :: DescriptorPoolCreateFlagBits | DESCRIPTOR_POOL_CREATE_HOST_ONLY_BIT_EXT specifies that this
descriptor pool and the descriptor sets allocated from it reside
entirely in host memory and cannot be bound. Similar to descriptor sets
allocated without this flag, applications can copy-from and copy-to
descriptors sets allocated from this descriptor pool. Descriptor sets
allocated from this pool are partially exempt from the external
synchronization requirement in
updateDescriptorSetWithTemplateKHR
and updateDescriptorSets. Descriptor sets
and their descriptors can be updated concurrently in different threads,
though the same descriptor must not be updated concurrently by two
threads.
|
| pattern DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BIT :: DescriptorPoolCreateFlagBits | DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BIT specifies that descriptor
sets allocated from this pool can include bindings with the
DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT
bit set. It is valid to allocate descriptor sets that have bindings that
do not set the
DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT
bit from a pool that has DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BIT
set.
