I've done threads in Java, but I'm a complete noob to threads in C. My first question, after googling some, is: Which thread library do I use? Does it matter? It seems I have thread.h and pthread.h to choose from.

OS is, and will be, Linux. More specifically, it's Ubuntu at the moment and will either stay like that, or become RHEL. But I guess the distro doesn't matter?

  • @pilcrow - didn't look in the file system, saw it in some tutorials, with methods like thr_create. It doesn't appear to be widespread, or maybe I got something wrong. I'm using pthreads now, so it doesn't matter anymore. Commented Mar 9, 2011 at 22:03
  • That's probably the native thread API of SunOS/Solaris, which might have answered your question right off the bat. :) Commented Mar 9, 2011 at 22:18
  • @pilcrow - You are very probably right. :) Commented Mar 9, 2011 at 22:36
  • The answer to this question helped me to overcome web search confusion, and after doing a lot of reading on POSIX threads, I realize just how newbie this question is. Hope it helps other noobs. Commented Mar 9, 2011 at 22:47

The POSIX thread libraries (pthread.h) are a standards based thread API for C/C++ and is what I would use. There are also several tutorials available such as this one or this one.

I will admit that I am not familiar with thread.h.

The standard thread interface on POSIX systems such as linux is pthread, for POSIX thread.
