<0> evening d.
<1> tnx Asmodee`
<2> C_Dreamer, are you around?
<2> c-bot fopen
<3> danimal, here you go: fopen - #include <stdio.h> FILE * fopen (const char *filename, const char *opentype) Opening Streams (ISO) see - http://www.msunix.co.uk/manual/glibc-2.2.3/html_chapter/libc_12.html#SEC178
<4> c-bot socket
<3> neax, here you go: socket - #include <sys/socket.h> int socket (int namespace, int style, int protocol) Creating a Socket (BSD) see - http://www.msunix.co.uk/manual/glibc-2.2.3/html_chapter/libc_16.html#SEC326
<2> c-bot, tell neax about beej
<3> neax, here you go: Beej"s Guide to Network Programming Using Internet Sockets - http://beej.us/guide/bgnet/
<2> just in case
<4> :)
<4> beej's guide to sockets is terrific
<2> yep, that's where i got my first taste of sockets
<2> c-bot, restrict
<5> That's new, I don't think it knows it.
<3> danimal, the magic 8 ball says... reply hazy, try again.
<5> It's an optimization keyword. It probably ought not have made it in, but it is there.
<4> c-bot ptr
<3> neax, the magic 8 ball says... better not tell you now.
<4> heh
<6> c-bot: pointe
<3> dbtid, stop smoking crack and ask again.
<6> c-bot: pointer
<3> dbtid, stop smoking crack and ask again.
<6> c-bot i love you
<3> dbtid, here you go: i love you too!
<6> actually i thought we had restrict in c-bot's database
<6> c-bot restrict
<3> dbtid, stop smoking crack and ask again.
<6> hrm
<6> odd
<6> c-bot snprintf
<3> dbtid, here you go: snprintf - #include <stdio.h> int snprintf (char *s, size_t size, const char *template, ...) Formatted Output Functions (GNU) see - http://www.msunix.co.uk/manual/glibc-2.2.3/html_chapter/libc_12.html#SEC196
<6> same db
<6> c-bot restrict
<3> dbtid, the magic 8 ball says... you're not making any sense; try again.
<6> c-bot VLA
<3> dbtid, here you go: Very Large Array radio telescope in Arizona or New Mexico
<6> c-bot long+long
<3> dbtid, the magic 8 ball says... concentrate and ask again.
<6> c-bot vfscanf
<3> dbtid, here you go: vfscanf - #include <stdio.h> int vfscanf (FILE *stream, const char *template, va_list ap) Variable Arguments Input Functions (ISO) see - http://www.msunix.co.uk/manual/glibc-2.2.3/html_chapter/libc_12.html#SEC216
<6> c-bot inline
<3> dbtid, stop smoking crack and ask again.
<7> ok, why is this happening?
<7> http://rafb.net/p/jR1KRN62.html
<7> the printf outside the for loop prints a higher value
<7> than inside the loop
<2> byte is unintialized
<7> ??
<2> how long have you been doing C?
<7> not so long
<7> i thought char *byte = malloc(8);
<7> did it
<7> not the case?
<7> why does strlen change during this loop?
<7> http://rafb.net/p/q9yTBn56.html
<7> why does strlen() change values here?
<7> http://rafb.net/p/q9yTBn56.html
<8> Considering that the code, as written, is completely nonfunctional, couldn't say for sure.
<7> the only difference
<7> is that binary exists
<7> the funciton looks like foo(char *binary)
<8> And what value does it have coming in?
<7> "011011110110110101100111"
<7> if i add a printf that checks the strlen before the loop, it checks out fine
<7> but its changing during
<8> FWIW, a quick test locally says it isn't changing.
<7> hmm
<8> This is why the 12th commandment is "Create a standalone test case". Otherwise who can test the code? :)
<9> So, I'm having an awful time with this reading off of sockets. Here's what I got. http://rafb.net/p/88YCzK57.html
<2> c-bot tell Mel_ about beej
<3> Mel_, here you go: Beej"s Guide to Network Programming Using Internet Sockets - http://beej.us/guide/bgnet/
<9> does it cover blocked reading? I have been using Beej's guide all along, but I didn't see anything about blocked reading
<0> what's the problem?
<2> yes
<2> select is blocking
<2> by default
<9> if there isn't data on the socket, then it hangs. So the first iteration reads and allocates, but the second iteration is blocking, waiting for a message, doesn't see that there's nothing on the socket...should I set the read to nonblock?
<0> Mel_: you seem to mishandle strings.
<9> yeah, heh, I need to brush up on that at some point...I just want to get this project done for this cl*** at this point :)
<2> its suppose to block if there's no data, that's why its called blocking
<0> fixing your string handling is integral to getting your code to work.
<9> hmmmm
<0> you have a loop. you return only the last count of bytes read. doesn't seem too useful if there were 12 receives that were successful.
<9> ahh yeah i just added the loop, i forgot to move that up
<0> so you receive 100 bytes. strlen(out) is 0. so you allocate space for 100 bytes. then you copy 101 bytes.
<0> sizeof (char) is always 1.
<0> you call strlen quite a lot.
<9> is strlen expensive?
<8> Yes.
<0> just wondering why you bother when recv provides a count.
<8> Technically, strlen doesn't _have_ to be expensive... but in practice, it is.
<9> yeah i suppose it would be easier to total the recvd bytes
<0> have you considered what happens if you receive all 256 bytes you request?
<9> that's what I'm trying to account for...
<0> well, all 256 bytes of tmp are written to, so you have no trailing \0 to terminate it as a string, thus a mistake to use it in strcat.
<8> Or what happens if the sender sends a buffer longer than the size you're reading - meaning there's no \0 for your strcat to end on?
<9> arg stupid interprited languages ****ing with my conceptions of string handling...
<0> there's no need to use strcat (any string handling) if you'll keep a counter.
<0> further, you misuse realloc.
<9> i'm a C failure.
<2> Mel_, its completley curable
<9> do they make a drug for it?
<8> Yes; it comes in this novel format known as "books". :)
<10> -.-
<11>
<12> =_=
<8> She gots, she gots. :)
<11> =^.^=
<11> hey You! :)
<11> ~
<8> Wrong channel, silly. :)
<11> newp
<11> it's communication thru ascii ;)
<11> it's like 'performance art'
<11> Tamama, Squeeeez and I were all just getting to know each other :)
<10> That is ok.. It is always quiet here anyway
<8> Well, hell, don't let me stop you. :)
<12> thank you blu^
<11> oh, my pleasure
<11> it's 'always' quiet?
<11> :/
<8> Pretty much. Feel free to add some color. :)
<11> omg! there's a novel idea
<11> they'd all prolly die of shock!! lol
<11> so... 57 people and almost NO chatting.. what's up with that?
<11> cyfo%y fo

<12> we're waiting for the next meal >:)
<12> omg
<13> Tamama doesn't want to be loved
<8> Depends, I suppose, how one defines "loved". :)
<13> Right, c-bot is just your jealous lover
<12> if I multiply two 127bit numbers together... this might give a 254bit number, right?
<6> what happens when you multiply 2 8 bit numbers?
<6> or 2 16 bit numbers?
<6> you do the math.
<12> true...
<12> thank you
<12> and sorry for the dumb questions
<6> not dumb
<6> just trying to prod you to think about the problem in other ways
