HOW TO GET IP INTERFACE INFORMATION
|
|
|
|
Some UNIX V.4 machines implement a sockets library on top of
|
|
streams. For these systems, you must use send the SIOCGIFCONF down
|
|
the stream in an I_STR ioctl. This ususally also implies
|
|
USE_STREAMS_DEVICE FOR IF_CONFIG. Dell UNIX is a notable exception.
|
|
|
|
WHAT DOES IOCTL(SIOCGIFCONF) RETURN IN THE BUFFER
|
|
|
|
UNIX V.4 machines implement a sockets library on top of streams.
|
|
When requesting the IP interface configuration with an ioctl(2) calll,
|
|
an array of ifreq structures are placed in the provided buffer. Some
|
|
implementations also place the length of the buffer information in
|
|
the first integer position of the buffer.
|
|
|
|
SIZE_RETURNED_IN_BUFFER - size integer is in the buffer
|
|
|
|
WILL IOCTL(SIOCGIFCONF) WORK ON A SOCKET
|
|
|
|
Some UNIX V.4 machines do not appear to support ioctl() requests for the
|
|
IP interface configuration on a socket. They appear to require the use
|
|
of the streams device instead.
|
|
|
|
USE_STREAMS_DEVICE_FOR_IF_CONFIG - use the /dev/ip device for configuration
|
|
|
|
MISC
|
|
|
|
DOSYNCTODR - Resync TODR clock every hour.
|
|
RETSIGTYPE - Define signal function type.
|
|
NO_SIGNED_CHAR_DECL - No "signed char" see include/ntp.h
|
|
LOCK_PROCESS - Have plock.
