Description

This extension allows applications to directly query a host pointer for a VkDescriptorSet which can be used to copy descriptors between descriptor sets without the use of an API command. Memory offsets and sizes for descriptors can be queried from a VkDescriptorSetLayout as well.

There is currently no specification language written for this extension. The links to APIs defined by the extension are to stubs that only include generated content such as API declarations and implicit valid usage statements.

This extension is only intended for use in specific embedded environments with known implementation details, and is therefore undocumented.
