Duplication of all threads or A new process with only one thread

I got the below info from  http://tldp.org/FAQ/Threads-FAQ/Problems.html
" The POSIX 1c standard defines a thread calling fork() to duplicate
only the calling thread in the new process; and an execve() from a
thread would stop all threads of that process."

OOps ?!?!

Hence it would be impossible to spawn a new process from a multithreaded
process.

How would you do this ?

Usually, the new forked process (inheriting only one thread) is
calling execve() and not the multithreaded process that calls fork()
in one of its threads.

-- hns

I see: the child created with fork is considered to be a new process and
not a thread of the parent process.

That brings up the question: how to create a new thread. But don't
bother, I'll be using the pthread library to do that for me :).

Thanks,

The usual way:

fork (creates a new process with only one thread running) ->
execve (replaces the process image).

Thanks. hat is how I had supposed it would be done. I was confused by
the cited text.
