Well....  I took the .c file mentioned previously, and compiled it on a 
Solaris 10 8/11 instance.  The 25-odd sockets it created *were* listed 
in the output of netstat -an -- local address as *.<portnum> remote 
address as *.* and a state of "BOUND."

A FreeBSD  (rev 8 IIRC) netstat -an seems to display them in a state of 
"CLOSED."  I didn't check HP-UX 11i v3 or AIX 6.
