! 50: HOW TO GET IP INTERFACE INFORMATION
! 51:
! 52: Some UNIX V.4 machines implement a sockets library on top of
! 53: streams. For these systems, you must use send the SIOCGIFCONF down
! 54: the stream in an I_STR ioctl. This ususally also implies
! 55: USE_STREAMS_DEVICE FOR IF_CONFIG. Dell UNIX is a notable exception.
! 56:
! 57: WHAT DOES IOCTL(SIOCGIFCONF) RETURN IN THE BUFFER
! 58:
! 59: UNIX V.4 machines implement a sockets library on top of streams.
! 60: When requesting the IP interface configuration with an ioctl(2) calll,
! 61: an array of ifreq structures are placed in the provided buffer. Some
! 62: implementations also place the length of the buffer information in
! 63: the first integer position of the buffer.
! 64:
! 65: SIZE_RETURNED_IN_BUFFER - size integer is in the buffer
! 66:
! 67: WILL IOCTL(SIOCGIFCONF) WORK ON A SOCKET
! 68:
! 69: Some UNIX V.4 machines do not appear to support ioctl() requests for the
! 70: IP interface configuration on a socket. They appear to require the use
! 71: of the streams device instead.
! 72:
! 73: USE_STREAMS_DEVICE_FOR_IF_CONFIG - use the /dev/ip device for configuration
! 74:
! 75: MISC
! 76:
! 77: DOSYNCTODR - Resync TODR clock every hour.
! 78: RETSIGTYPE - Define signal function type.
! 79: NO_SIGNED_CHAR_DECL - No "signed char" see include/ntp.h
! 80: LOCK_PROCESS - Have plock.
