You use pthreads. There are various implemenations available that
work to varying degrees with different libraries.
Check http://www.globenet.it/~ermmau/Threads/ for general info on
threads under Linux.
Check maybe http://pauillac.inria.fr/~xleroy/linuxthreads/ for info on
the Linux Threads package (kernel based threads).
Check http://www.mit.edu:8001/people/proven/pthreads.html for
Provenzano's user space implementation of pthreads (and man pages for
pthreads).
Check
http://www.sun.com/sunsoft/Products/Developer-products/sig/threads/index.html
for general info on threads.
Note that as far as I know, none of these threads packages
interoperate well with the X libraries. If you want to use both
threads and X, then you need to recompile the X libraries with
-D_REENTRANT.
If you don't want to recompile X yourself, You can get copies of the X
libraries compiled -D_REENTRANT from the VIBE package. VIBE is a
product from VISIX. Java IDE which incorporates the GALAXY class
library. There's a free beta for linux available from them. Connect
to http://www.visix.com to get the package.
