I am trying to access files in a folder. The folder name and location will be given - the program will search inside the files in that folder for a specific pattern(yup like grep). However, I am not sure how to actually let my program know what are the files available and access them one by one.

I could use pipe in unix or linux. As for Win XP I could only think of using the system("dir > tmpfilename") and thus saving the output it into a temporary file. Then taking the file names from that file.

Please let me know if anyone of you have a better idea as how to do the job. I cannot use win32 because the program would be used as an example in a class introducing the C programming language. So it means no C++ as well. Is there any way to make the code portable(I doubt)?

On MS-Windows, use FindFirstFile() and FindNextFile(). There are lots of examples how to use those two functions floating around, just use google to search for them.

How to get those filenames is an os-specific task -- you will have to use win32 api functions. Yes, they can be used in console applications, just include windows.h. And it does not require any knowlege of c++. But it does require a little more then absolute beginner's knowledge. Need to know about loops, and structures and character arrays. If that is too much then you probably should pick a different example.
