Use the +following defines: + +=over 4 + +=item B + +Return the hostname of the host the iterator points to. Since the name is +looked up using the socket address this may differ from the hostname passed to +ping_host_add(3). The hostname is actually looked up every time you call this +method, no cache is involved within liboping. + +It is recommended to include C and allocate B bytes of +buffer. + +=item B + +Return the address used in ASCII (i.e. human readable) format. The address is +looked up every time you call this method. 40 bytes should be sufficient for +the buffer (16 octets in hex format, seven colons and one null byte), but more +won't hurt. + +=item B + +Returns the address family of the host. The buffer should be ig enough to hold +an integer. The value is either B or B. + +=item B + +Return the last measured latency or less than zero if the timeout occured +before a echo response was received. The buffer should be big enough to hold a +double value. + +=item B + +Return the last sequence number sent. This number is increased regardless of +echo responses being received or not. The buffer should hold an integer. + +=item B + +Return the ident that is put into every ICMP packet sent to this host. Per +convention this usually is the PID of the sending process, but since liboping +can handle several hosts in parallel it uses a (pseudo-)random number here. The +buffer should be big enough to hold an integer value. + +=back + +The I argument is a pointer to an appropriately sized area of memory +where the result of the call will be stored. The I value is used as +input and output: When calling B it reports the size of +the memory region pointed to by I. The method will write the number of +bytes actually written to the memory into I before returning. + +=head1 RETURN VALUE + +B returns zero if it succeeds. + +B is returned if the value passed as I is unknown. Both, +I and I, will be left untouched in this case. + +If the requested information didn't fit into I then the size that would +have been needed is written into I; I itself is left +untouched. The return value is B in this case. + +=head1 SEE ALSO + +ping_iterator_get(3), +liboping(3) + +=head1 AUTHOR + +liboping is written by Florian octo Forster Eocto at verplant.orgE. +It's homepage can be found at L. + +(c) 2005, 2006 by Florian octo Forster.
