%SECTION0{name=Threads}% Threads

If you need multithreading, using POSIX threads will give your application
portability, even to non-Linux embedded systems. For example, they're supported
by EL/IX (see [[http://sources.redhat.com/elix/]]), 
%REF{type=Section,topic=Alternatives,name=eCos,text=eCos}%,
%REF{type=Section,topic=Alternatives,name=RTEMS,text=RTEMs}%,
and virtually all desktop systems.

POSIX threads support is supplied with glibc2 as an add-on, enabled by
configuring with ='--enable-add-ons=linuxthreads'=.

It is also possible to build older (i.e. smaller) libc5 with LinuxThreads. See
[[http://pauillac.inria.fr/~xleroy/linuxthreads/faq.html]]

LinuxThread support has now been integrated into the official *gdb* release
(currently 5.0), which makes thread debugging much easier. Versions of *gdb*
prior to 5.0 did not support threads directly, although you can 'attach' to the
thread processes individually.

The courageous can also call =clone()= directly.
