  13     NAME
  14         PrintNetFault - socket error messages
  15
  16     SYNOPSIS
  17         PrintNetFault(code, banner)
  18         void PrintNetFault(LONG, const UBYTE *)
  19
  20     FUNCTION
  21         The PrintNetFault() function finds the error message corresponding
  22         to the code and writes it, followed by a newline, to the standard
  23         error or Output() filehandle. If the argument string is non-NULL it
  24         is preappended to the message string and separated from it by a
  25         colon and space (`: '). If string is NULL only the error message
  26         string is printed.
  27
  28     NOTES
  29         The PrintNetFault() function uses the DOS IO functions.
