Course in Threads Programming using Modern C++

Course in C++ threads programming based on POSIX Threads as well as the new standard C++ 11/14/17

Bugs in multi-threaded programs are often seen as the most troublesome issue one can get as a programmer. The general advise use to be to not put them there from the beginning.

If one think that advise is unrealistic, the next best is to code according to several well-proven programming-idioms which avoid the problems. In this course we focus on that strategi.

This course partly overlap with our course "POSIX & C11 Threads Programming using C", but differ in that it also encapsulate all C data-types in better C++ classes, and of course a thorough walk-through of threads in C++11/14/17.

This is what you will learn
  • Writing multi-threaded programs using POSIX Threads API
  • Writing multi-threaded programs in C++ based on class wrappers around the C Api
  • Writing multi-threaded programs in C++11
  • Understand and know how to deal with classical concurrency problems such as critical-sections, race-conditions and deadlocks
  • Using mutex locks and condition variables both in POSIX and C++11
  • Understand and know how to deal with promises/futures in C++1
