I have a bunch of file handling code that I am writing in VC++ 6.0. I am mostly using the methods defined in <io.h> such as _finddata_t structure , _chdir(), rename(), _getcwd() and alike. At sime point it might be necessary to compile the application I am coding on a Linux platform. I don't think these methods are unix compatible. I don't have any experience coding on a linux/unix platform. I need to know if there are any file handling modules that can be compatible on both platforms or a way to make minimal changes to the existing code which makes it possible to compile it on a linux platform.
Any suggestions or reference to a resource(online, books,...) is appreciated.
