Yes, this is what I was afraid of.

I assume you are talking about tcpip_try_callback() right? Only thing I
could find about tcpip_trycallback() is this:

tcpip_trycallback() was renamed to tcpip_callbackmsg_trycallback() to avoid 
confusion
    with tcpip_try_callback()

It seems that the name was (and still is) very confusing (;

Anyway tcpip_try_callback() does indeed look as what I could use for my
purpose, so thanks for info! I'll try that tomorrow, however I'm not
sure how will I be able to deal with an error when posting the callback
(or allocating the message) will not be possible. The other function -
tcpip_callbackmsg_trycallback() -  also looks like I could use it, one
possible failure point less.
