Hi,

I asked this question on freebsd-smp...I'm asking here in case
anyone has any ideas.

I am the port maintainer for the Apache Portable Runtime (APR) library.

APR makes use of a function in Linux called
atomic_dec_and_test which is described here:

http://kernelnewbies.org/documents/kdoc/kernel-api/r287.html

Is there a way that I can use the existing <machine/atomic.h>
FreeBSD macros to achieve the equivalent of atomic_dec_and_test?

I couldn't figure out a way to do it.

Thanks.
