I’m seeing a lot of usages of sleep 0 in my one of my client project. The code look something like this. Reading through some of the answer of SO like this it seems that sleep 0 has some significance. What I want to known now is that does scheduling for other thread to run (if they are waiting to

How to programmatically prevent linux computer from sleeping or turning on screensaver?
While developing a small cross-platform game on C++, I got stuck with following issue: when players are playing with a USB gamepad without touching a keyboard or mouse, the computer sleeps automatically while they’re playing. In Windows, it can be done easily using SetThreadExecutionState function. In OS X, I think it can be done with UpdateSystemActivity but not tested yet.
How can my Linux program get a computer-is-about-to-go-to-sleep notification, without modifying any system config files?
I wrote a Linux program that creates some persistent TCP connections, and I would like my program to close() those TCP sockets just before the Linux-computer goes to sleep, so that the remote peer isn’t left with a non-responsive “zombie” TCP connection. According to this answer, one way to do that is to modify the /etc/pm/sleep.d file to run a
SIGALRM, interval timers and problems with sleep()
I am working with porting one of our embedded microcontroller libraries to linux and writing a python wrapper around it. One of my low level modules depends on a callback that gets called every 10ms. This callback counts up software timers that each have callbacks of their own. These timers are used all over our library and while they don’t
nasm assembly linux timer or sleep
I’m trying to find a way to make my code wait for two seconds before proceeding. I’m using nasm for Linux in protected mode, so I can only use int 80h. I found a syscall called “alarm” (27) and another called “pause” (29). However, when I try to use those, the program waits and finishes instead of continuing execution. I’ve
