Comments:
<0> thank heavens, we're saved
<1> glukak nieu jaar
<1> or some such
<2> i think Cowmoo doesn't want to be friends with me
<2> bealtine: gelukkig nieuwjaar
<2> but it's not really the moment
<1> close
<0> solely based on the stupid comment you made earlier, perhaps not
<1> its all i know in dutch
<2> Cowmoo: i know
<2> first impression is crucial
<3> Off to office
<4> heh, if cowmoo was friends only with people that didn't ridicule him constantly, he'd have no friends at all
<4> wait
<4> clearly that's the case
<5> hi guys.. was thinking of havin a struct something like this.. but not allowed. i'm looking for a better implementation or advice. "struct temp { int type; int nSize; char strData[nSize]; int temps; }" any help in strData?
<6> you could use an STL string
<6> if that is what you are asking
<1> or a vector
<4> K_r3aPeR: the compiler always needs to know the size of things
<5> hmm.. but declaring it's size? cause I want to memcpy() some data into the struct directly..
<1> ogh so C
<4> if you're stuck on the C way of doing things, I'd suggest a MAX_SIZE macro
<4> heh
<5> peterhu, yeah that's it.. the problem is the size of it.. im reading from a packet of data.. and memcpy() it into the struct temp
<5> so the length would vary
<5> bealtine, is memcpy() really bigtime to be not in c++?
<1> i just use a vector
<6> if you are set on doing ikt the way you have it now, you need to use a pionter and hten allocate memory for it
<5> cn28h, huh? sample?
<4> or have strData use a constant size which is the maximum amount of data it can hold, and have strData's declaration come last
<5> bealtine, i still dont understand how vector helps
<6> char *p; p = new char[100]; /* this is not ususally the best way to do things, but it works */
<1> you can set the size
<5> cn28h, erngh.. sorry.. that doesnt help
<6> why not?
<1> he just see the 100
<5> peterhu, declare a constant size? that'd overlap into temps or underlap sometimes.. when i set a constant of 100, but the packet/data only has 50.. then where will temps be?
<4> which is why i said strData needs to come after temps
<5> peterhu, ahh ok i got ur point.. but the *PACKET* has the temps after the strdata
<5> which is having me problems
<4> clearly not written by a good C developer
<5> i dunno if it's not really written good.. it's from a GAME..
<4> so then use a maximum expression and forget the memcpy
<5> maximum expression?
<5> read each data and ***ign ?
<4> const int MAX_SIZE = 100; struct temp { ... char strData[MAX_SIZE + 1]; ... }; ... /* read packet */ temp t; memcpy(t.strData, packetData, packetDataLen > MAX_SIZE ? MAX_SIZE : packetDataLen); /* does it need a null? */
<4> christ does C ****
<6> that wouldn't be valid C ;P
<4> yeah
<7> i think when having structs like that wiht many diffrent datatype members you should always do a #pragma
<7> dunno if its related
<4> #define MAX_SIZE 100
<4> heh
<1> your original "christ does C ****" comment still stands :)
<5> hmm.. lemme read it clear
<6> I'm currently doing a project ofr work that is completely in C heheh
<1> why C ?
<1> no compiler ?
<6> kernel code
<6> (BSD)
<1> big swinging **** ?
<5> peterhu, sorry.. but the whole PACKET is.. the TEMP itself
<1> couldnt resist :)
<6> you've been hanging around peterhu too much
<5> so -> temp t; memcpy(t, packetData, packetDataLen)
<1> eh?
<6> that's not going to work
<1> you want to shove the whole packet in one struct ?
<1> apart from the syntax errors...
<4> honestly, what programmer writes his packets so that variable sized data is sandwiched between fixed sized data?
<5> yeap that's it
<5> the whole packet in one struct
<1> oh gawd
<5> i have all of my other packets in one struct.. am just stuck on this one which contains the STRING part
<4> what's "temps" supposed to hold?
<6> the time, maybe
<1> how do you know how long the "string" supposed to be?
<5> temps hold some value in-game.. that i still dunno yet.. a DWORD it should be
<5> bealtine, the string's length is the INT before the start of the string
<1> so what wrong with a pointer then?
<4> he needs to read in 4 bytes (***uming 32 bit int) into "type", 4 bytes into size, allocate a buffer of size "size" (***uming there's no max), read in "size" number of bytes, read in 4 bytes into "temps"
<5> a pointer? and when I allocate the whole struct? defeats the purpose
<1> ummm
<5> peterhu, yep
<1> why would you do that?
<5> so I'd not memcpy() this then.. any better advice?
<1> a vector usuulay works fine for me ymmv
<8> yah
<8> make ur own memcpy
<5> i read my packet till I reach the SIZE?
<8> say standard library, you ****ing ****
<8> i'll ****ing kill the standard library
<1> got that off your chest then?
<5> thanks for your time guys
<5> i'll re-think all of your advices
<4> K_r3aPeR: http://www.noidea128.org/sourcefiles/16346.html
<4> might give you some ideas
<4> it should really have a sizeof(char) in there, and you could avoid a second string copy if you wanted to, but i just pounded it out to give you some ideas
<4> oh, and noidea128 formating blows hard
<0> for the millionth time, rafb.net/paste
<4> std::vector<char> buffer => std::vector < char >buffer? blech
<4> pfft
<4> rafb sounds dubious
<0> which says nothing about its functionality
<0> f00l
<1> thats so efnet
<0> too bad, since it's rather superior
<4> everyone should use sourceforge
<0> if rafb had a compile option then it would be superior to sf
<0> sf looks like poo
<4> http://cpp.sourceforge.net/
<4> far superior
<4> even compiles it
<0> my statement still stands
<4> plus, it's editable
<0> oh, true
<0> but still rafb looks better
<0> mo betta
<4> pfft
<4> you = baffoon
<9> I have a program that is going to spit position data several times a second, so I don't want to use fprint, etc. What is the easist way to have the program make one line that says "Position: XX" where the XX is updated, without printing a whole new line?
<0> I really wish NI would either improve his pastebin or the link would be to another more competent one
<0> the link in topic, that is
<1> we wish for many things
<0> Christoph66: eh? is creating a function ok?
<4> Christoph66: firstly, fprintf is a legacy C function and rarely used by C++ developers; secondly, you would have to seek backwards from the write to write again
<0> ohh
<9> peterhu: yeah fprint was simply an example of printing a whole new line. OK, what function or library should I look at for the functionality
<4> seekp is what you want on fstream
<4> lunch time
<4> bbl
<9> ok thanks
<5> peterhu, tnx
<10> today is Update Tuesday!
<10> Microsoft Windows updaten
<6> ich ben rebooten
<11> how do you perform simple addition in c++?|
<11> cout<<x+y;
<11> ?
<0> ?
<11> oh.
<0> where are all you people coming from
<0> with your strange question
<0> s
<11> z = x + y; | cout>>z;
<0> <<
<12> cout<<z;
<11> i am a beginner
<12> cout<<z<<endl;;
