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.

What next?
|
||
----------
|
||
|
||
- Experiment with the worked examples in the QL for C/C++ topics: :doc:`Function classes <function-classes>`, :doc:`Expressions, types and statements <expressions-types>`, :doc:`Conversions and classes <conversions-classes>`, and :doc:`Analyzing data flow in C/C++ <dataflow>`.
|
||
- Find out more about QL in the `QL language handbook <https://help.semmle.com/QL/ql-handbook/index.html>`__ and `QL language specification <https://help.semmle.com/QL/ql-spec/language.html>`__.
|
