Introducing the C/C++ libraries
|
||||
===============================
|
||||
|
||||
Overview
|
||||
--------
|
||||
|
||||
There is an extensive QL library for analyzing snapshots extracted from C/C++ projects. The QL classes in this library present the data from a snapshot database in an object-oriented form and provide abstractions and predicates to help you with common analysis tasks. The library is implemented as a set of QL modules, that is, files with the extension ``.qll``. The module ``cpp.qll`` imports all of the core C/C++ library modules, so you can include the complete library by beginning your query with:
|
||||
|
||||
.. code-block:: ql
|
||||
|
||||
import cpp
|
||||
|
||||
The rest of this topic summarizes available QL classes and corresponding C/C++ constructs.
|
||||
|
||||
NOTE: You can find related classes and features using the query console's auto-complete feature. You can also press **F3** to jump to the definition of any element; QL library files are opened in new tabs in the console.
|
||||
|
||||
Summary of the library classes
|
||||
==============================
|
||||
|
||||
The most commonly used standard QL library classes are listed below. The listing is broken down by functionality. Each QL library class is annotated with a C/C++ construct it corresponds to.
|
||||
|
||||
Declaration classes

||||
-------------------
|
||||
|
||||
This table lists `Declaration <https://help.semmle.com/qldoc/cpp/semmle/code/cpp/Declaration.qll/type.Declaration$Declaration.html>`__ classes representing C/C++ declarations.
