Very Computer

Hello there!
I want to port to Linux the InterORB library from Solaris.
And it uses threads.
Could anyone very wise tell me how should it be (in general) done.
I've noticed that Linux uses MIT threads (<pthread.h>) instead of
solaris <thread.h> and don't really know differences.
Is there any library that MUST be linked to executable file for using
thread on Linux (like -lthread switch is Solaris makefiles)?
I'm using Slackware 3.0 (kernel 2.0.0 without any patches)
                I will be VERY gratefull for ANY help.
                (this is important for my diploma)
                Thank you!
                        Tom

I don't know about "MIT" threads, the pthreads I have are POSIX
threads, and are as close to a standard as we have. Linux offers two
implementations of pthreads, one using user level threads which has
very low overhead but can get blocked and only uses one CPU, and one
using the clone() system call to thread at the kernel level.

Actually I should say "two types of thread implementations," since
there are several instances of each type. Mine are all somewhat old
by now, so I'd rather not give you versions numbers, but look on
sunsite for various packages.

All of the pthreads libs I have are compatible at the source level,
although the ones using clone() are less apt to block and run much
faster on an SMP machine.
