<0> if p is declared as char * p, then you should use p = &x;
<1> Question: How much will the waterlevel fall if one removes the water from all the worlds oceans?
<2> 10924 meters
<3> uhm
<3> depends how deep the seabed is, basically
<2> in that case 10924 meters
<1> How did you arrive at that number?
<2> it is the deepest spot in all the worlds oceans
<2> Mariana Trench
<1> you serious? now or what?
<1> I thought you were being facetious
<2> yes
<2> Mariana Trench is 10924 meters deep
<1> How about this: If you pour 50kg of icecubes into a bathtub, how much will the waterlevel have have been raised after they've melted?
<2> http://maps.google.com/maps?f=q&hl=en&q=11+21+0.+142+12+0.&ll=11.781325,142.207031&spn=37.540739,85.429688&t=k
<2> afters they've melted compared to what?
<1> I rather do believe that the waterlevel raises when you pour the icecubes into the water and not when they've melted as they displace the same amount of water as their m*** which, when melted, equals that.
<2> yes ;D so how much did the waterlevel raise from which point?
<2> so which numbers do we compare ?
<1> It doesn't say that it specifically has to be from before the icecubes are poured into the water.
<2> but could it be?
<1> It's a mindgame, of sorts.
<2> true ;)
<1> :)
<2> the waterlevel may have dropped before all the ice is melted
<1> how so?
<2> if it's warm and dry air the water will become fumes
<2> what kind of expression you say that ?
<2> that also depends on the size of the bathtub ;P
<1> :)
<1> Hahaha - CNN, a mans brother-in-law bit his finger off and was holding it hostage ... Only in New York
<2> =D
<2> that can only be happening in america ;)
<1> yea lol
<2> I couldn't imagine that happening on my neighborhood ever :D there are never even hostage situation

<5> hubertEF- a pointer to an array?
<4> what are those ()s for?
<5> so that it's not an array of pointers?
<4> what now - array or not? :)
<4> <5> so char x[] = 7001, (*p)[] = &x; would work?
<5> hmm
<4> what are you trying to do?
<5> p*** a number to getaddrinfo()
<5> iniofs?
<4> getaddrinfo(42)?
<5> getaddrinfo(NULL, port, &hints, &res);
<5> port
<5> specifically
<5> the others seem to work fine
<4> 2nd argument is servname here...?
<5> yep
<4> const char * restrict servname
<4> wtf is 'restrict'?
<5> it's a C99 thing
<5> the apple man page has const char *servname
<5> restrict means something can only be accessed as a pointer
<6> iT's char *
<7> can someone tell me how i get wpa_supplicant it said its included in netbsd 4.0
<7> but i dont seem to have it is it a kernel option i must enabled
<4> mspo:
<4> The hostname and servname arguments are either pointers to NUL-terminated
<4> strings or the null pointer
<4> The servname is either a deci-
<4> mal port number or a service name listed in services(5).
<1> ask on freenode
<1> they probably know
<4> mspo: if you want to specify a number, you have to convert it to a string first, see sprintf(3)
<4> char portstr[999];
<4> sprintf(portstr, "%d", 6667);
<4> i'm sure there are ways better functions than sprintf() security wise, but I don't know them. maybe something like snprintf() or asprintf()
<6> snprintf
<4> Be sure to use the proper secure idiom:
<4> snprintf(buffer, sizeof(buffer), "%s", string);
<6> although he could stuff it in a char
<4> he could just use a hardcoded service name (string) :)
<4> but what do I know
<6> yes as in the example
<4> hmmm
<5> I mean
<5> can't I just say "char foo[] = 7001; "?
<4> no
<4> because the thing on the right side of the = is no string
<5> what if I put it in " " or ' '?
<4> and for an array initialisation, you need to p*** exactly that
<6> 7001 is an integer
<4> char foo[] = "7001";
<4> that'd work
<6> and not a null terminated char array
<2> foo is not a valid example
<4> note that this leaves out the size of the 'foo' array, and lets the C compiler determine the size
<5> but for getaddrinfo, I need to say *foo[] = "7001";
<5> char *foo[] = "7001";
<4> d00d
<2> http://exposed.coldfront.net/?226
<4> there's big honking difference between a char foo[], a char *foo, and a char *foo[]
<5> d00d, I need to review pointers? :)
<4> d00d, indeed :)
<6> or check out the grocery store:)
<4> heh
<6> http://home.netcom.com/~tjensen/ptr/ch1x.htm
<5> char *port = "7001"; compiled
<5> hmm
<5> ah, because it's the same as port[] = "7001"
<5> because char's are pointers
<4> no.
<6> a char can be a for example. A string is an array of chars
<4> or a pointer to an array of chars ;)
<6> a pointer points to a memory location
<6> and may point to a char array
<5> I thought a char was an array of int's. And &char pointed to int[0]
<4> what is a char?
<6> char = "character" which can also be represented as an integer
<5> char is an array of int's ending with \0 (null)
<4> mspo: no.
<6> No, mspo, you are conpusing types
<6> confusing
<4> <6> conphusing
<6> a char cannot hold "mspo" for example as it is one byte
<4> char == byte (character)
<4> with a byte usually having 8 bits (and let's not not go into signed vs. unsigned now)
<4> int == an integer with usually 32bit
<4> and I don't recommend trying to mess with the internals of an 'int' as being composed of several 'char's
<4> (think "byte order")
<5> so let's say I wanted to store a string like "7001 is the port"
<4> grab some space to hold the text, then copy in the single bytes
<5> char str[18] = "7001 is the port"; is incorrect?
<4> yes
<4> but 17 would be enough ;)
<4> if you want to save the counting, you can use []s in that case, and the compiler will figure it out
<6> for "mspo" you need five bytes
<5> yes it's incorrect, or yes it's correct?
<4> yes, correct syntax
<5> okay
<4> 'str' identifies the start of the space of 17 (18?) chars
<5> 17 + \0 ?
<4> it has the address of the first character
<5> right
<5> so if I said
<4> miyu% echo -n '7001 is the port' | wc -c
<4> 16
<5> char *str = "7001 is the port";
<4> 16 + '\0' = 17 :)
<5> okay, I might me miscounting :)
<5> so you were saying char *foo is different from char foo[] ?
<5> #include <stdio.h>
<8> I never did grok pointers
<5> int main() {
