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.

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.

void vkGetDescriptorSetLayoutHostMappingInfoVALVE(
    VkDevice                                    device,
    const VkDescriptorSetBindingReferenceVALVE* pBindingReference,
    VkDescriptorSetLayoutHostMappingInfoVALVE*  pHostMapping);

Valid Usage (Implicit)

• device must be a valid VkDevice handle
• pBindingReference must be a valid pointer to a valid VkDescriptorSetBindingReferenceVALVE structure
• pHostMapping must be a valid pointer to a VkDescriptorSetLayoutHostMappingInfoVALVE structure

void vkGetDescriptorSetHostMappingVALVE(
    VkDevice                                    device,

    void**                                      ppData);

Valid Usage (Implicit)

• device must be a valid VkDevice handle
• descriptorSet must be a valid VkDescriptorSet handle
• ppData must be a valid pointer to a pointer value
• descriptorSet must have been created, allocated, or retrieved from device
