\chapter{Conclusion}\label{ch:conclusion}
Lorem Ipsum.
This work presented \texttt{intercept.so}, a shared object file intended to be preloaded using \texttt{LD\_PRELOAD}, which may be used to intercept function calls on Linux systems.
Furthermore, a tool to use this shared object easier---the \texttt{intercept} Python program---was presented.
By using preloading to hook/intercept function calls, the overhead and performance degradation is negligible for the purpose of testing student submissions.
To make use of intercepted function calls, some techniques of automatic testing of simple C programs were discussed.
The source code of the programs developed in this work is attached below.
(Not all PDF viewers may open/download attachments.)
\texttt{intercept.so}:
\textattachfile{../proj/intercept/src/intercept.c}{\textcolor{blue}{\texttt{intercept.c}}} (source code), and
\textattachfile{../proj/intercept/Makefile}{\textcolor{blue}{\texttt{Makefile}}}.
\textattachfile{../proj/intercept/intercept}{\textcolor{blue}{\texttt{intercept}}} (Python program).
Automatic testing: \textattachfile{src/attachments/auto-test.zip}{\textcolor{blue}{\texttt{auto-test.zip}}} (zipped Python programs).
