Thanks for the rapid response!!!

Yessir.

I turned on -Wall (I thought I already had!) well, it pointed out that
I was making a pointer to an int by using write(stdout.....) instead
of write(fileno(stdout)... 

So, that pretty much solved that problem.  Boy, do I feel like an idiot.

Anyhow, I encountered a race condition with test10.c if I make the
output more than the size of the send_buffer (32).  Do you also get
that?  I made a solution and if you'd like I'd be more than happy to
contribute!
