C Specification

If the pNext chain of a VkDescriptorSetLayoutCreateInfo or VkDescriptorPoolCreateInfo structure includes a VkMutableDescriptorTypeCreateInfoEXT structure, then that structure specifies Information about the possible descriptor types for mutable descriptor types.

The VkMutableDescriptorTypeCreateInfoEXT structure is defined as:

// Provided by VK_EXT_mutable_descriptor_type
typedef struct VkMutableDescriptorTypeCreateInfoEXT {
    VkStructureType                          sType;
    const void*                              pNext;
    uint32_t                                 mutableDescriptorTypeListCount;
    const VkMutableDescriptorTypeListEXT*    pMutableDescriptorTypeLists;
} VkMutableDescriptorTypeCreateInfoEXT;

or the equivalent

// Provided by VK_VALVE_mutable_descriptor_type
typedef VkMutableDescriptorTypeCreateInfoEXT VkMutableDescriptorTypeCreateInfoVALVE;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • mutableDescriptorTypeListCount is the number of elements in pMutableDescriptorTypeLists.

  • pMutableDescriptorTypeLists is a pointer to an array of VkMutableDescriptorTypeListEXT structures.

Description

If mutableDescriptorTypeListCount is zero or if this structure is not included in the pNext chain, the VkMutableDescriptorTypeListEXT for each element is considered to be zero or NULL for each member. Otherwise, the descriptor set layout binding at VkDescriptorSetLayoutCreateInfo::pBindings[i] uses the descriptor type lists in VkMutableDescriptorTypeCreateInfoEXT::pMutableDescriptorTypeLists[i].

Valid Usage (Implicit)

  • VUID-VkMutableDescriptorTypeCreateInfoEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_MUTABLE_DESCRIPTOR_TYPE_CREATE_INFO_EXT

  • VUID-VkMutableDescriptorTypeCreateInfoEXT-pMutableDescriptorTypeLists-parameter
    If mutableDescriptorTypeListCount is not 0, pMutableDescriptorTypeLists must be a valid pointer to an array of mutableDescriptorTypeListCount valid VkMutableDescriptorTypeListEXT structures
