Atomic instructions on HPUX

How is it possible to use atomic operations instructions with aCC on HPUX 11.00 ?

Thanks

Laurant,
I suspect you're looking for the load-clear-word instruction (LDCWS on PA) for atomic locking? The easiest way is to write a small function in assembler and call it from C/C++.

If you look at Linux kernel sources for PA-RISC, you should find the required inlined assembler code. Then the excercise is just to turn it to an aCC version.
