Pthreads – a few random tips and FAQs

To conclude this chapter, we provide answers to FAQs on multithreading as well as a brief note on how to debug a MT application using GDB. Do read on.

Every function in your MT application that can be run in parallel by threads must be written, verified, and documented to be thread-safe. This includes your MT app code, your project libraries, as well as any third-party libraries you link into.

Pthreads – some FAQs

Q: What happens in a multithreaded process when a thread calls one of the exec*() routines?
A: The calling application (the predecessor) is completely replaced by the successor process, which will be only the thread that called exec. Note that no TSD destructors...

He is the author of a book “Linux 2.4 Kernel Internals” which is available in several languages at the Linux Documentation Project. He worked at VERITAS as a Linux Kernel Architect, improving the kernel and teaching OS internals. For the Bible societies Tigran produced scholarly Bible editions in Hebrew, Greek, Syriac, Slavonic and ancient Armenian. Recently he published “The British Study Edition of the Urantia Papers”. He is currently working on the foundations of Quantum Mechanics on a branch of physics called Quantum Infodynamics.

Kaiwan N. Billimoria

Kaiwan N. Billimoria taught himself BASIC programming on his dad's IBM PC back in 1983. He was programming in C and Assembly on DOS until he discovered the joys of Unix, and by around 1997, Linux! Kaiwan has worked on many aspects of the Linux system programming stack, including Bash scripting, system programming in C, kernel internals, device drivers, and embedded Linux work. He has actively worked on several commercial/FOSS projects. His contributions include drivers to the mainline Linux OS and many smaller projects hosted on GitHub. His Linux passion feeds well into his passion for teaching these topics to engineers, which he has done for well over two decades now. He's also the author of Hands-On System Programming with Linux, Linux Kernel Programming (and its Part 2 book) and Linux Kernel Debugging. It doesn't hurt that he is a recreational ultrarunner too.
