VkDescriptorSetLayoutCreateInfo(3)

# VkDescriptorSetLayoutCreateInfo(3) Manual Page

## Name

VkDescriptorSetLayoutCreateInfo - Structure specifying parameters of a newly created descriptor set layout

## C Specification

Information about the descriptor set layout is passed in a `VkDescriptorSetLayoutCreateInfo` structure:

    typedef struct VkDescriptorSetLayoutCreateInfo {
        VkStructureType                        sType;
        const void*                            pNext;
        VkDescriptorSetLayoutCreateFlags       flags;
        uint32_t                               bindingCount;
        const VkDescriptorSetLayoutBinding*    pBindings;
    } VkDescriptorSetLayoutCreateInfo;

## Members

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to an extension-specific structure.

- `flags` is a bitmask of VkDescriptorSetLayoutCreateFlagBits specifying options for descriptor set layout creation.

- `bindingCount` is the number of elements in `pBindings`.

- `pBindings` is a pointer to an array of VkDescriptorSetLayoutBinding structures.

## Description

Valid Usage

- The VkDescriptorSetLayoutBinding::`binding` members of the elements of the `pBindings` array must each have different values.

- If `flags` contains `VK_DESCRIPTOR_SET_LAYOUT_CREATE_PUSH_DESCRIPTOR_BIT_KHR`, then all elements of `pBindings` must not have a `descriptorType` of `VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC` or `VK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC`

- If `flags` contains `VK_DESCRIPTOR_SET_LAYOUT_CREATE_PUSH_DESCRIPTOR_BIT_KHR`, then all elements of `pBindings` must not have a `descriptorType` of `VK_DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK_EXT`

- If `flags` contains `VK_DESCRIPTOR_SET_LAYOUT_CREATE_PUSH_DESCRIPTOR_BIT_KHR`, then the total number of elements of all bindings must be less than or equal to VkPhysicalDevicePushDescriptorPropertiesKHR::`maxPushDescriptors`

- If any binding has the `VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT` bit set, `flags` must include `VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT`

- If any binding has the `VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT` bit set, then all bindings must not have `descriptorType` of `VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC` or `VK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC`

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_DESCRIPTOR_SET_LAYOUT_CREATE_INFO`

- `pNext` must be `NULL` or a pointer to a valid instance of VkDescriptorSetLayoutBindingFlagsCreateInfo

- `flags` must be a valid combination of VkDescriptorSetLayoutCreateFlagBits values

- If `bindingCount` is not `0`, `pBindings` must be a valid pointer to an array of `bindingCount` valid VkDescriptorSetLayoutBinding structures
