## C Specification

The VkGraphicsPipelineLibraryCreateInfoEXT structure is defined as:

// Provided by VK_EXT_graphics_pipeline_library
typedef struct VkGraphicsPipelineLibraryCreateInfoEXT {
VkStructureType                      sType;
void*                                pNext;
VkGraphicsPipelineLibraryFlagsEXT    flags;
} VkGraphicsPipelineLibraryCreateInfoEXT;

## Members

• sType is the type of this structure.

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

• flags is a bitmask of VkGraphicsPipelineLibraryFlagBitsEXT specifying the subsets of the graphics pipeline that are being compiled.

## Description

If a VkGraphicsPipelineLibraryCreateInfoEXT structure is included in the pNext chain of VkGraphicsPipelineCreateInfo, it specifies the subsets of the graphics pipeline being created, excluding any subsets from linked pipeline libraries. If the pipeline is created with pipeline libraries, state from those libraries is aggregated with said subset.

If this structure is omitted, and either VkGraphicsPipelineCreateInfo::flags includes VK_PIPELINE_CREATE_LIBRARY_BIT_KHR or the VkGraphicsPipelineCreateInfo::pNext chain includes a VkPipelineLibraryCreateInfoKHR structure with a libraryCount greater than 0, it is as if flags is 0. Otherwise if this structure is omitted, it is as if flags includes all possible subsets of the graphics pipeline (i.e. a complete graphics pipeline).

Valid Usage (Implicit)
• VUID-VkGraphicsPipelineLibraryCreateInfoEXT-sType-sType
sType must be VK_STRUCTURE_TYPE_GRAPHICS_PIPELINE_LIBRARY_CREATE_INFO_EXT

• VUID-VkGraphicsPipelineLibraryCreateInfoEXT-flags-parameter
flags must be a valid combination of VkGraphicsPipelineLibraryFlagBitsEXT values

flags must not be 0
