Description

This extension allows applications to directly query a host pointer for a DescriptorSet 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 DescriptorSetLayout as well.

Note

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.

Note

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

Stub API References

There is currently no specification language written for this command. This section acts only as placeholder and to avoid dead links in the specification and reference pages.

// Provided by VK_VALVE_descriptor_set_host_mapping
void vkGetDescriptorSetLayoutHostMappingInfoVALVE(
    VkDevice                                    device,
    const VkDescriptorSetBindingReferenceVALVE* pBindingReference,
    VkDescriptorSetLayoutHostMappingInfoVALVE*  pHostMapping);

Valid Usage (Implicit)

• device must be a valid Device handle

• pBindingReference must be a valid pointer to a valid DescriptorSetBindingReferenceVALVE structure
• pHostMapping must be a valid pointer to a DescriptorSetLayoutHostMappingInfoVALVE structure
