Analyzing data flow in C/C++
============================
Analyzing data flow in C and C++
================================
Overview
--------
You can use data-flow analysis to track the flow of potentially malicious or insecure data that can cause vulnerabilities in your code base.
This topic describes how data flow analysis is implemented in the CodeQL libraries for C/C++ and includes examples to help you write your own data flow queries.
The following sections describe how to utilize the libraries for local data flow, global data flow, and taint tracking.
