File handling in Linux

Prommy · 07-04-2003, 07:47 AM

Hi.
I'm quite new to Linux programming and is trying to do a little c program that involves some file handling. If I would like to do something like getting directory listings, moving files, etc. from my program, how is that done? Right now my program simply calls a bash script that does the file handling stuff, but that feels like just going round the problem.

I've searched all over the web with no result...

why not look at the open close and stat system calls. also have you looked at the source for ls / mv / cp?

Yes I have. Problem there is that it's quite much code to read through...

why? how many of your favorite programs rely on other, smaller programs to get the job done? what about programs like xcdroast, which are little more than just front ends to other programs (cdrecord in this case)? the whole *NIX deal is not re-invent the wheel. if it's there (especially standard tools like ls and mv), use it. If a bash script feels crappy, use popen().

My program encounter error with the header file #include<fcnt1.h>

Some document states that this header file which is to handle some
files-handling.

Please give me the advise! Thanks you !

If it's the same library i think it is then it's <fcntl.h> with an l and not a 1.

If C filehandling doesn't work for you, you might want to check out Perl's, it's basically the same thing, but a bit simpler (i found). You also use fcntl in Perl

Thanks Prommy,

You're right !It's fcntl.h !

I will continue this program because I am not very fimilar with Perl programming.

Thank you for guidances!
