# VkPhysicalDeviceToolPropertiesEXT(3) Manual Page

## Name

VkPhysicalDeviceToolPropertiesEXT - Structure providing information about an active tool

## C Specification

The VkPhysicalDeviceToolPropertiesEXT structure is defined as:

    typedef struct VkPhysicalDeviceToolPropertiesEXT {
        VkStructureType          sType;
        void*                    pNext;
        char                     name[VK_MAX_EXTENSION_NAME_SIZE];
        char                     version[VK_MAX_EXTENSION_NAME_SIZE];
        VkToolPurposeFlagsEXT    purposes;
        char                     description[VK_MAX_DESCRIPTION_SIZE];
        char                     layer[VK_MAX_EXTENSION_NAME_SIZE];
    } VkPhysicalDeviceToolPropertiesEXT;

## Members

- `sType` is the type of this structure.

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

- `name` is a null-terminated UTF-8 string containing the name of the tool.

- `version` is a null-terminated UTF-8 string containing the version of the tool.

- `purposes` is a bitmask of VkToolPurposeFlagBitsEXT which is populated with purposes supported by the tool.

- `description` is a null-terminated UTF-8 string containing a description of the tool.

- `layer` is a null-terminated UTF-8 string that contains the name of the layer implementing the tool, if the tool is implemented in a layer - otherwise it may be an empty string.

## Description

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_TOOL_PROPERTIES_EXT`

- `pNext` must be `NULL`
