VkDescriptorGetInfoEXT

Structure specifying parameters of descriptor to get

Information about the descriptor to get is passed in a VkDescriptorGetInfoEXT structure:

typedef struct VkDescriptorGetInfoEXT {
    VkStructureType sType;
    const void* pNext;
    VkDescriptorType type;
    VkDescriptorDataEXT data;
} VkDescriptorGetInfoEXT;
  • sType is a VkStructureType value identifying this structure.
  • pNext is NULL or a pointer to a structure extending this structure.
  • type is the type of descriptor to get.
  • data is a structure containing the information needed to get the descriptor.
