VkDescriptorAddressInfoEXT

Data describing a VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER, VK_DESCRIPTOR_TYPE_STORAGE_BUFFER, VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER, or VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER descriptor is passed in a VkDescriptorAddressInfoEXT structure:

typedef struct VkDescriptorAddressInfoEXT {
    VkStructureType sType;
    void* pNext;
    VkDeviceAddress address;
    VkDeviceSize range;
    VkFormat format;
} VkDescriptorAddressInfoEXT;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• address is either 0 or a device address at an offset in a buffer, where the base address can be queried from vkGetBufferDeviceAddress.
• range is the size in bytes of the buffer or buffer view used by the descriptor.
• format is the format of the data elements in the buffer view and is ignored for buffers.

If the nullDescriptor feature is enabled, address can be zero. Loads from a null descriptor return zero values and stores and atomics to a null descriptor are discarded.
