I'm working on a project that has to be portable (Windows, Linux, Unix (IDE is VisualC++) ). What I need is the list of files in a certain directory (+subdirs), but I also need to know some file attributes like size and 'date of last change'. Anybody knows a lib that can do this for me? Thanks in advance Janina [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

Anybody knows a lib that can do this for me? opendir() is rather portable, though it is not part of ANSI C, but rather POSIX. Thus, you'll find it on Linux, Solaris, AIX, IRIX, HPUX and similar, to be found in <dirent.h> in conforming systems. It is not an ANSI-C or C++ function; these know nothing about the concept of 'directories'. I afraid you won't get around writing your custom headers and make the decision on a couple of #define's. File dates can be obtained thru stat, though that's again only POSIX and not ANSI-C/C++. Headers for stat are <sys/stat.h> and/or <unistd.h>.

I strongly recommend the filesystem library of boost. Have look at boost.

Look at www.boost.org/libs/filesystem. The version in the Boost CVS has a few additional features you might also be interested in. --Beman Dawes [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

Look at the Boost filesystem library at: http://www.boost.org/libs/filesystem/doc/index.htm As it has been pointed out this is fairly portable (Linux/Unix/Windows/Posix (this means in this context Mac OS X, Linux, Unix, Solaris, BSD etc.) Make sure you read its portability guide, a link from the page I have posted. -- Attila aka WW [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

COBOLs! Don't use #defines, use your make file (or whatever) to select the *.c in your platform dependent directories. Louis.

Anybody knows a lib that can do this for me? http://boost.org/libs/filesystem/doc/index.htm might meet your requirements. But don't limit your investigation of boost to just the filesystem library: boost has a lot to offer. [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.
