CMSG_DATA man page

[Luke Small]

I used the example from the man page and it worked  in the program only one
time in a session. I found example code on the web that introduces a one
byte message (that I ignore) along with the ancillary data and it works at
least twice in a receiving session. Is it a bug in the implementation, the
man page or both? I'm on my iPhone now, but I could send you the example
code later.
