<0> hi everyone
<0> im having some problems with special chars..
<0> printf("l\x86dan"); gives me c:\Skolarbeten\Del2\del2_b\del2_b.c(33): error C2022: '34522' : too big for character
<0> but if i: printf("l\x86 dan"); it works
<0> anyone know a way around this?
<0> on the later one i get a space char that isnt supposed to be there
<1> printf("l\x86%s", "dan")
<0> hmm.. is that the only way?
<1> there are probably others
<0> is there a way to limit \x86? so it dosnt include a-f chars after it?
<1> conver x86 into decimal
<0> float?
<1> int
<2> printf("l\x86" "dan");
<0> thanks Xirtam, worked like a charm :)
<0> anyone remember how to put statements within printf?
<0> like: printf("text month%s\r\n", months>1("s"));
<3> you could do
<3> %c and months>1?'s':' '
<3> or
<3> "\0s"[months>1]
<0> thanks dbtid :)
<0> is fgets + atoi the best way to get integers from the keyboard?
<2> strtol() is better than atoi().
<0> ok, thanks :)
<4> What do FTP servers do when file send fails durring a file upload? Are partial files ever written? does ftp protocol cover this?
<5> Asmodee`: I ordered that K&R second edition book
<5> I found this other book at work, that seems to have a signed short integer range error
<5> it says -32767 to 32767
<5> shouldn't it be -32768? am I wrong?
<6> Nope, it's right.
<6> The book, that is.
<5> hrm
<5> doesn't counting start at -1 with the negatives, though?
<6> ***ume a signed-magnitude machine; values range 0..32767, then add a sign bit.
<4> does any part of the ftp protocol require rename files durring upload to a temporary file name until they are fully uploaded?
<5> bitrot: I'm just looking at it from this angle
<5> I have 15 bits of numbers, and 1 bit that stores the sign
<5> 15 bits of numbers give me 32768 different values, that start at 0 for positive
<5> so positive range is 0-32767
<5> negative range should be -1 to -32768
<5> that's my logic
<6> No, total range is 0..32767; you have 15 value bits. Now add a sign, it;s 0..32767 or -0..-32767
<5> oh
<5> I see
<5> so false ***umption that negative counting begins at -1
<6> On *some* machines, they actually go -32768...32767... but that's not required... because other machines can't do it (without going to a bigger type, and what's the point of that?)
<5> just following the rules of math, I would think it would go to -32768
<5> I mean, wtf is -0? =)
<6> Math doesn't have to deal with umpteen different bit representations in hardware.
<6> It's a 0 value with the sign bit set.
<6> Your compiler is expected to be smart enough to treat -0 and 0 as equal... but they have different bit patterns on such machines.
<5> I see
<7> I've actually never seen -0
<6> One would think a compiler worth its salt would tend to convert automatically... however, the bit pattern is, AIUI, perfectly valid.
<7> hmm. salty compiler
<5> sudo woman -c getinthekitchenandmakememydinner
<8> ty
<5> Asmodee`: thanks for the K&R recommendation. I'm reading it now.
<5> it's a little terse but they are definitely more to the point about what is considered to be C functionality and itself and what is provided by external functions.
<9> thnks
<10> where I can find make bnf?
<11> hi, how do i set a socket to be non-blocking ? i've googled and came up with fcntl(socket, F_SETFL, O_NONBLOCK); but upon using this i get http://www.rafb.net/paste/results/N7y3yH59.html
<11> i've included fcntl.h.
<12> why are you using the winsocks 1.1 library?
<11> didn't think i needed the winsock 2 for this.. just started playing with winsock. so is it because i'm using winsock 1.1 ?
<12> anyway, are you sure you have the right header(s) included?
<12> no -- i'm just wondering why you are using the ancient interface.
<11> these are the headers i have included http://www.rafb.net/paste/results/UPYGj547.html
<11> fcntl.h is there.. though yea, it looks as if i need to include something else too :-\.. just don't know what.
<12> what does your documentation for fcntl an O_NONBLOCK say?
<11> i got the info on the non-blocking socket here: http://www.manualy.sk/sock-faq/
<11> it says
<11> Technically, fcntl(soc, F_SETFL, O_NONBLOCK) is incorrect since it clobbers all other file flags. Generally one gets away with it since the other flags (O_APPEND for example) don't really apply much to sockets. In a similarly rough vein, you would use fcntl(soc, F_SETFL, 0) to go back to blocking mode.
<11> ow, seems i have you have to include unistd.h on some systems too.
<11> same error :-\
<11> can't find nothing in my headers about F_SETFL/O_NONBLOCK.. these are the headers i've got with devcpp 4.9.8.0.. guess they're missing something.
