"man clone" is a good starting place.

In Linux, threads are almost the same thing as processes. Obviously, there
are differences, but basically, that is true. Both are created via clone(2). (fork() is implemented on top of clone()).

No, I haven't, that's why I'm asking questions. If you won't help me,
why don't you just go find your lost manhood elsewhere.

Exactly.
In the early 2000's, the Linux kernel moved to supporting 1:1 threads,
and provided the NPTL ("Native Posix Threading Library") to provide the
POSIX application-level API to this new kernel capability.

Is that defined by POSIX threads, or is it something specific?

It is how Linux implements the kernel-level responsibilities of POSIX
threads.

Is there any good link to read more about that?

Plenty. Google "NPTL and Linux"

(My thread times have long passed; I used it from C++, and there were
a lot of things to consider when programming with threads back then.)
