string splitting plzzzzzz help me...

[xyz]

I have a string
16:23:18.659343 131.188.37.230. 22 131.188.37.59.1 398 tcp 168

for example lets say for the above string
16:23:18.659343 -- time
131.188.37.230 -- srcaddress
22 --srcport
131.188.37.59 --destaddress
1398 --destport
tcp --protocol
168 --size
i need to split the string such that i need to get all these
parameters....
the field widths are not fixed..i have some times four/three digits
srcport ..so i cant do it with substr function...i need this in c++
i am not getting an idea how to split it..
thank you for any help

the clue is '.' so read function as many you want according to each
field...

Then post in <news:comp.lang .c++>, as it is not topical in this group.

i am not getting an idea how to split it..

You could start by splitting the spaces. Then determine which from the
splitted tokens are ipv4 addresses (do you care about ipv6?) and
strrchr(str, '.')
The solution seems very easy. I suggest you go back to learning the
basics before you start writing networking code.

You have posted the same post four times in an hour. You are not
going to increase the level of response by being obnoxious. Show what
code you have developed so far and many will provide additional help.
Ask us to do the work for you and suffer in silence.

hi,
You can also use space (' ') to break the original strings and then
parse on the individual strings (after separating it on space taken)
to get your results.

Well, I think plzzzzzz retired a few years ago, but maybe I can help.

Find below the portable C code of a program that splits a string very
similar to the one above into its components.

Enjoy.

Lcc-win32, or at least your copy of it, has errors.

No, the lcc standard library is breaking conformance by declaring
and defining a function outside of the implementation namespace.
That is not John's fault.

[...]

"wtof" is not defined in the C standard, and a conforming
implementation is not allowed to declare it in <stdlib.h>.

Perhaps this is corrected in a newer version of lcc-win32? As a
workaround, you can change the name "wtof" to something else.

Probably because LCC-WIN32 fails to observe the C standard. There
is no such function as "wtof" in the C library.
