For these systems, you must use send the SIOCGIFCONF down 41 the stream in an I_STR ioctl. This ususally also implies 42 USE_STREAMS_DEVICE FOR IF_CONFIG. Dell UNIX is a notable exception. 43 44 WHAT DOES IOCTL(SIOCGIFCONF) RETURN IN THE BUFFER 45 46 UNIX V.4 machines implement a sockets library on top of streams. 47 When requesting the IP interface configuration with an ioctl(2) calll, 48 an array of ifreq structures are placed in the provided buffer. Some 49 implementations also place the length of the buffer information in 50 the first integer position of the buffer. 51 52 SIZE_RETURNED_IN_BUFFER - size integer is in the buffer 53 54 WILL IOCTL(SIOCGIFCONF) WORK ON A SOCKET 55 56 Some UNIX V.4 machines do not appear to support ioctl() requests for the 57 IP interface configuration on a socket. They appear to require the use 58 of the streams device instead. 59 60 USE_STREAMS_DEVICE_FOR_IF_CONFIG - use the /dev/ip device for configuration 61 62 MISC 63 64 DOSYNCTODR - Resync TODR clock every hour. 65 RETSIGTYPE - Define signal function type. 66 NO_SIGNED_CHAR_DECL - No "signed char" see include/ntp.h 67 LOCK_PROCESS - Have plock. 68 */ 69 70 int ntp_set_tod (struct timeval *tvp, void *tzp);
