Getting started with tools used in laboratories

Lab0: Introduction to C and the pthread API

A quick introduction by example to C syntax, data type and their use, functions, modules, as well as spawning and waiting for threads. Find another introduction from former Lab 0 of the course "Concurrent programming and Operating Systems" (TDDB68), which include more C-related issues such as pointer management.
