libwacom Documentation

# Introduction

libwacom is a library to identify wacom tablets and their model-specific features. It provides easy access to information such as "is this a built-in on-screen tablet", "what is the size of this model", etc.

# Usage

The usage of libwacom in an application could look like this:

         WacomDeviceDatabase *db;
         WacomDevice *device;
         WacomError *error;

         db = libwacom_database_new();
         error = libwacom_error_new();
         device = libwacom_new_from_path(db, "/dev/input/event0", WFALLBACK_NONE, error);
         if (!device)
              return; // should check for error here

         if (libwacom_device_is_builtin(device))
              printf("This is a built-in device\n");

         libwacom_destroy(device);
         libwacom_database_destroy(db);

# Database

libwacom comes with a database of models and their features in key-value format. If you cannot use libwacom, the files may be parsed directly. Note that the file format may change over time, especially in the beginning.
