  The terse setsockopt dept 
 The Question is:
 
I have an (DEC C) application build on OpenVMS V6.2 with UCX V4.1. Until now I
 have had no problems running it on all similar or higher version platforms but
 I have just discovered that it does not run on V7.2-1 with TCPIP V5.0A
 
The failing function is :
 
setsockopt(sock,IPPROTO_TCP,TCP_NODELAY,&amp;1,1)
 
What to do ? I do not want to have multiple binaries !
 
 The Answer is:
 
  Without a full source code example (reproducer), without specific details
  of the failure (errno value, signal(s) seen, etc), and without details of
  the remote system(s) you are operating with, an answer is difficult.
 
  Please contact the Compaq Customer Support Center.  Expect to be asked
  the version of the C compiler (later compiler versions are better at
  reporting latent coding errors that might be lurking), the failure(s)
  seen, details of the remote system, and for an example of the failing
  C code involved.
