  The terse errno dept 
 The Question is:
 
Where can I find what a errno 4002 error for TCP/IP?
 
 The Answer is:
 
  Interesting.
 
  Is this Compaq TCP/IP Services?
 
  Do you have an example of the C code that produces that errno code,
  as the OpenVMS Wizard does not immediately see that code (4002 decimal)
  listed anywhere obvious in the TCP/IP Services V5.0A references.
 
  Is this returned via errno or vaxc$errno?  Does the perror call help?
  Is DECthreads or some other C-related package in use here?  Example
  code?
