VkDescriptorGetInfoEXT(3)

C Specification

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

// Provided by VK_EXT_descriptor_buffer
typedef struct VkDescriptorGetInfoEXT {
    VkStructureType        sType;
    const void*            pNext;
    VkDescriptorType       type;
    VkDescriptorDataEXT    data;
} VkDescriptorGetInfoEXT;

Members

sType is the type of 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.
