/**
 * Structure specifying parameters of a newly created descriptor pool.
 * 
 * 
Description
* *

If multiple {@link VkDescriptorPoolSize} structures appear in the {@code pPoolSizes} array then the pool will be created with enough storage for the total number of descriptors of each type.

* *

Fragmentation of a descriptor pool is possible and may lead to descriptor set allocation failures. A failure due to fragmentation is defined as failing a descriptor set allocation despite the sum of all outstanding descriptor set allocations from the pool plus the requested allocation requiring no more than the total number of descriptors requested at pool creation. Implementations provide certain guarantees of when fragmentation must not cause allocation failure, as described below.

* *

If a descriptor pool has not had any descriptor sets freed since it was created or most recently reset then fragmentation must not cause an allocation failure (note that this is always the case for a pool created without the {@link VK10#VK_DESCRIPTOR_POOL_CREATE_FREE_DESCRIPTOR_SET_BIT DESCRIPTOR_POOL_CREATE_FREE_DESCRIPTOR_SET_BIT} bit set). Additionally, if all sets allocated from the pool since it was created or most recently reset use the same number of descriptors (of each type) and the requested allocation also uses that same number of descriptors (of each type), then fragmentation must not cause an allocation failure.

* *

If an allocation failure occurs due to fragmentation, an application can create an additional descriptor pool to perform further descriptor set allocations.

* *
