## Name

VkGraphicsPipelineLibraryCreateInfoEXT - Structure specifying the subsets of the graphics pipeline being compiled

Loading… please wait.

## C Specification

The `VkGraphicsPipelineLibraryCreateInfoEXT` structure is defined as:

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

## Members

- `sType` is a VkStructureType value identifying 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

- VUID-VkGraphicsPipelineLibraryCreateInfoEXT-flags-requiredbitmask
  `flags` must not be `0`
