# VkLayerProperties(3) Manual Page

## Name

VkLayerProperties - Structure specifying layer properties

Loading… please wait.

## C Specification

The `VkLayerProperties` structure is defined as:

    // Provided by VK_VERSION_1_0
    typedef struct VkLayerProperties {
        char        layerName[VK_MAX_EXTENSION_NAME_SIZE];
        uint32_t    specVersion;
        uint32_t    implementationVersion;
        char        description[VK_MAX_DESCRIPTION_SIZE];
    } VkLayerProperties;

## Members

- `layerName` is an array of `VK_MAX_EXTENSION_NAME_SIZE` `char` containing a null-terminated UTF-8 string which is the name of the layer. Use this name in the `ppEnabledLayerNames` array passed in the VkInstanceCreateInfo structure to enable this layer for an instance.

- `specVersion` is the Vulkan version the layer was written to, encoded as described in https://registry.khronos.org/vulkan/specs/latest/html/vkspec.html#extendingvulkan-coreversions-versionnumbers.

- `implementationVersion` is the version of this layer. It is an integer, increasing with backward compatible changes.

- `description` is an array of `VK_MAX_DESCRIPTION_SIZE` `char` containing a null-terminated UTF-8 string which provides additional details that can be used by the application to identify the layer.
