hi there
can any one write a C code that search for files in a directory
without using the windows apis(FindFirstF ile() and FindNextFile())
or even has a small idea on how to do that.
thanks.

No.
I use the MSDN library for that purpose.

I would imagine that using the Windows APIs would be fairly useless
on non- MS Windows systems, so if we take it as understood that
people have indeed been able to write code to search for files in
a directory on at least one non- MS Windows system, then the answer
to your question would logically have to be "Yes".
You might find it instructive to read the recent thread "directorie s"
started by 'sid' on June 27th, http://groups.google.ca/group/comp.l...23538a011bd637

No.
ANSI C has no directory functions, which at first sight may seem surprising
since there are fucntions to open files from paths.
However on many systems directories can be very large, and can be altered by
other users. This makes it quite difficult to devise a robust interface
which will hold for every system.
Thus you have to use OS-specific functions.

yes i know that ANSI C has no directory functions,to make my question
clear,how can i write a function that search for files using a native
C code (without using Windows APIs)i know it's possible to write that
code, the obvious example is the windows APIs
themselves(Find FirstFile() and FindNextFile()) if it's not possible how
these two functions are coded?

Technically, with the proper 3rd-party addon, anyone can write this. In
fact, given my current platform, I can definitely write a directory search
program in C (with POSIX extensions) without using /any/ Windows APIs. It
helps that I don't run Windows, of course ;-)
or even has a small idea on how to do that.
thanks.

It seems as though:
1 Those functions are your examples of functions
coded in "native c code".
2 You have no idea how those functions are coded.
Am I reading you correctly?

There is no requirement that Windows API functions are coded in C. For
all we know, they're coded in assembler. There are many ways to make
functions available to C without writing those functions themselves in
C, though the techniques are off-topic here.
There is _no_ portable way to do what you're asking. C does not even
acknowledge that directories exist, since C has to work on platforms
that have no concept of directories. Therefore, there is no 100%
portable way to write code that manipulates or even examines directories.
The usual solution when running into problems like this is to create
your own wrapper interface and a few different implementations (with
suitable #ifdef's) that call the native functions. Of course, at that
point your program is only "portable" to the systems that implement one
of the native interfaces you know how to call...

As i know(i've heard) and i'm not sure that windows APIs are coded in
C and those two functions are part of Windows APIs.if i'm wrong you
can correct me not just tell me that i'm wrong coz this is not
