Chapter 29. Primitive Thread Synchronization Constructs

In this chapter:

Class Libraries and Thread Safety

Primitive User-Mode and Kernel-Mode Constructs

User-Mode Constructs

Kernel-Mode Constructs

When a thread pool thread blocks, the thread pool creates additional threads, and the time and memory resources required to create, destroy, and schedule threads is very expensive. When many developers see that they have threads in their program that are not doing anything useful, they tend to create more threads in hopes that the new threads will do something useful. The key to building scalable and responsive applications is to not block the threads you have so that they can be used and reused to execute other tasks. Chapter 27, focused on how to use existing ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
