i want to get size of a file (DOS/LINUX), I use fopen to open file but i dont know how to obtain it's size.

I don't know anything about linux programming but maybe this filesize function from the HLA standard library will help.


#if( os.linux )

procedure fsize_handle( handle:dword ); @nodisplay;
fstat : linux.stat_t;

begin fsize_handle;

linux.fstat( handle, fstat );
if( eax = -1 ) then

raise( ex.FileReadError );

mov( fstat.st_size, eax );

end fsize_handle;

The stat function is a possibility, a more general way is seeking to the end of the file with fseek, then reading the file pointer with ftell.

P.S. What was this doing in the crusades? Moved it to the heap :).

fseek() with SEEK_END + ftell()?

ah Thomas beat me :D

thx all

you know it was about C and stuff......

BTW Hiro can you add this emoticon to this board ???

well, yes if you can tell me what it means :)

BTw have you seen Samurai Deeper Kyo? it's great

It's not that easy to explain but i will try.

So you can use it when someone say or do something stupid. When you say something idiotically obvious and make big case about this.
damn it is hard to explain

Yep i have seen Samurai deeper kyo and it was nice anime. But you can find more interesting animes out there.

about this emoticon:
for example we are on a anime board and someone tell us that "Akira" is stupid and boring anime.

we can answer (or dont answer at all to such a question :tongue: )

Becouse we just cant measure "Akira" just like that.

:alright: (that's a pity its not the luckyest example :cool: )

But returning to my previous question.

Can you tell me why fseek is bigger than ftell ???
Posted on 2003-12-10 17:14:53 by AceEmbler

you should do something like

filesize = ftell(pStream);

then filesize will contain the size in bytes of the file

Err=FEnd - FBegin;
printf("size %d\n",Err);

i made something like this and the size was -87 (my file size is 87)
Posted on 2003-12-10 18:41:53 by AceEmbler
well FEnd has to be 0 for that to work

0 - 87.... :)

The file size can be different though, if you opened it in ascii mode. Then CR/LFs might be translated into something else, so that fseek+ftell will give you a different value than the raw filesize that stat gives you.

what is CR and LFs.

BTW Hiro what about this emoticon ??

Carriage return line feeds. windows makes use of CRLF while *nix makes use of LF. IIRC mac makes use of CR and thus windows is the cross breed between *nix and mac when it comes to pressing the enter button.

when you say ASCI mode it's the same as text mode yes ??
Posted on 2003-12-11 08:25:25 by AceEmbler
Yes :)

Posted on 2003-12-11 08:31:01 by Thomas
damn damn that C.

i have got a problem its probably about this asci mode you are talking about. I try to take bytes(characters) from:
My file contains such a chars. (bytes(dec))

93 13 10 91

when i take bytes after bytes

first is 93 second is 10 and third is 91
how can i read this thing properly ??
Posted on 2003-12-11 10:20:37 by AceEmbler
13=CR 10=LF. Read in binary mode and not ascii.

I've always used:

But I guess this isn't portable :rolleyes:
