sequantial processing of files of several directories

[kkirtac]

Hello, i will simply state algorithm of the problem :

root "r" = GetRootDirectory( );
foreach child directory "c" of "r"
foreach file "f" of "c"
process f ;
endfor
endfor

"process" is not important here, the main problem is how i can reach a
directory, how i can visit all of its childs and catch the files of
all childs sequentially.

Regards

off-topic I think

I can't see anything related to C++

anyway, there's a hint
File system operation is platform specified
On Windows, check out _FindFirstFile_ on MSDN, or _File_ in Java API

Since you gave psuedo code and haven't said what OS, etc.. I'll treat this
as an algorithm problem. Not totally OT but...

Normally I would use recursion for this.

root "r" = GetRootDirectory( );
ProcessDirectory( root );
// done

ProcessDirectory( path )
for each entry in path
if entry is file
process file
else if entry is path
ProcessDirectory( path )
endfor

Hello, i m sorry i am on a VC++ - Win32 Console project in Visual
Studio 2005..yes i think i need recursion..i m a bit
complicated..which class to use and how..anyway, wrong place to ask
maybe, thanks

Take a look at the faq, section 5.9 for some suggestions on where better
to ask this question: http://www.parashift.com/c++-faq-lite/
Also, msdn.microsoft.com is a good source and Barry suggested
FindFirstFile() which might be useful.

Check out the Boost library's file and directory support.

FWIW: wxWidgets has a nice set of classes for file/directory.
Most people think of wxWidgets as a GUI, but, it has a flag to turn off the
GUI build.
