Err... I ran an mqueue test and it popped up with ENOSYS. Which
makes me wonder, are POSIX mqueues implemented 100% on FreeBSD? I
looked into sys/kern/uip_mqueue.c and it _appears_ functional, but I
could be misreading the code. Another test written which tests mqueue
appears to be broken as well (I'll include that in a later email if
interested). I also attached the truss output and the relative code
blurb for a little more analysis.
Thanks,
-Garrett
PS I'm not guaranteeing that the code below doesn't have bugs in it as
I'm not the original author and the tests were originally written and
targeted towards Linux.
