I wish I knew what I am talking about:)

Seriously, as I said in the first posting, POSIX threads were not
completelly implemented before, e.i. you could not set stack/size
for threads. In different documents I have read about threads they
would explain :
"you don't have to worry about allocating memory for thread stack.
It will be done automatically" and so on.
I guess I posted a question here a few years ago and got conformation.

Now, it seems to me some Linux implementations support this, and as
David said, I can use ..setstack() function.
What I am saying is this function, dispite being POSIX standart 
function, is not supported under some Linux distributions.

I am using "uname -a" return value to check(know) if this function
is supported.

Whenever this function is supported, I call it "enterprize", sounds
funny, but all I am interested, about to somehow distinguish which 
machines I can run which function of POSIX standart thread library.

To wrap this up, I would like to put a question here:
Is it true some Linux distributions do not support pthread_attr_setsatck() ?

Examples of uname:
 >uname -a
Linux "some.machine.in.some.com" 2.4.9-31custom #1 SMP Wed Oct 16 
13:07:01 CDT 2002 i686 unknown

The last word "unknown" tells me about the system which does not support 
setstack.

 >uname -a
Linux "some.machine.in.some.com" 2.4.21-15.ELhugemem #1 SMP Thu Apr 22 
00:09:08 EDT 2004 i686 i686 i386 GNU/Linux

If the last word is GNU/Linux, then it supports it.

Thanks,
-haro
