Change log for iftop
$Id$
0.13
* Fixed configure.in to properly specify libraries without the leading -l
* Separated the IP/ethernet identifying routine from iftop.c into addrs_ioctl.c

Solaris:
On Solaris, libpcap does not capture outgoing packets unless it is run on an
interface in promiscuous mode. Therefore, you will need to use the -p option
to iftop to get sensible results. Cf.
http://www.tcpdump.org/lists/workers/2002/02/msg00010.html
On Solaris, iftop has to run in promiscuous mode in order to capture
outgoing packets. iftop autoconfigures to run in promiscuous mode on
Solaris, but will filter out non-broadcast packets which are not
addressed to or from localhost. On Solaris, the -p option merely
disables that filter.
If you have some other sort of system that behaves like Solaris in
needing promiscuous mode, you can pass --enable-default-promiscuous to
configure to enable this behavior.
Cf. http://www.tcpdump.org/lists/workers/2002/02/msg00010.html
The version of curses distributed with Solaris may not be sufficient for
iftop's needs. You will probably need ncurses or similar.

strncpy2()
strncpy2() is like strncpy(), except that strncpy2() will always
insure that the <dest> buffer is null terminated. strncpy() will not
NULL terminate the destination buffer if the <src> string is <n>
characters long or longer, not counting the terminating NULL character.
STRNCPY2() IS NOT A COMPATIBLE REPLACEMENT FOR STRNCPY()!!
There are two reasons to use strncpy2().
The first reason is to guarantee that <dest> buffer's bounds are not
violated. In this case, <n> should be the size of the <dest> buffer
minus one.
i.e.,
char tempstring[MAXLINE];
strncpy2(tempstring, my_own_string, MAXLINE - 1);
The second reason is to copy a specific number of characters from
<src> to <dest>. In this case, <n> should be the number of characters
you want to transfer, not including the terminating NULL character.
The following example copies "abc" into tempstring, and NULL
terminates it.
char tempstring[MAXLINE];
strncpy2(tempstring, "abcdef123", 3);
strncpy2() returns a pointer to the first character in <src> that was
not copied to <dest>. If all of <src> was copied to <dest>,
strncpy2() will return a pointer to the NULL character terminating the
<src> string.
------------------------------------------------------------------------------*/

strncpy2(char *dest, char *src, int n)

int
i = 0;
char
*char_ptr;

if ((!dest) || (!src))
return(src);
char_ptr = dest;
while ((i++ < n) && *src)
*char_ptr++ = *src++;

return(src);
}
/*------------------------------------------------------------------------------
strncat2()
Similar to strncat except that <n> is the size of the <dest> buffer
(INCLUDING SPACE FOR THE TRAILING NULL CHAR), NOT the number of
characters to add to the buffer.
STRNCAT2() IS NOT A COMPATIBLE REPLACEMENT FOR STRNCAT()!
strncat2() always guarantees that the <dest> will be null terminated, and that
the buffer limits will be honored. strncat2() will not write even one
byte beyond the end of the <dest> buffer.
strncat2() concatenates up to <n-1> - strlen(<dest>) characters from
<src> to <dest>.
So if the <dest> buffer has a size of 20 bytes (including trailing NULL),
and <dest> contains a 19 character string, nothing will be done to
<dest>.
If the string in <dest> is longer than <n-1> characters upon entry to
strncat2(), <dest> will be truncated after the <n-1>th character.
strncat2() returns a pointer to the first character in the src buffer that
was not copied into dest.. so if strncat2() returns a non-zero character,
string truncation occurred in the concat operation.

operation, or n if the concat operation got truncated.. a number
between 0 and n
We need to check src_ptr here because i will be equal to n if
<dest> was full before the concatenation operation started (which
effectively causes instant truncation even if the <src> string is
empty..
We could just test src_ptr here, but that would report
a string truncation if <src> was empty, which we don't
necessarily want. */
