  Missing TCP/IP Symbol Definition? 
 The Question is:
 
Running TCP/IP Services version 5.0.  My question is in regard to the socket
 option TCPIP$C_TCP_KEEPINIT.  It is listed in the documentation as a TCP/IP
 option, that you can set using the IO$_SETMODE.  I cannot find this option
 declared in any include fil
e on my system.  Am I missing something?  What include file should this be in?
 Thank you!
 
 The Answer is:
 
  This would be a bug, and a report has been passed along to the
  TCP/IP Engineering team -- the problem has been corrected in the
  V5.1 release.
 
  The correct symbol definitions (for V5.0 and V5.0A) are:
 
    #define INET$C_TCP_KEEPINIT    7
    #define TCPIP$C_TCP_KEEPINIT   7
