how to match files with a reference file in a folder?

Hi all,
My C program generates a image file of .jpg format (code written with the aid of opencv library).Now I have a database folder containing many images.I wanted to match (correlate) the generated image file with each and every file sequentially with the files in the database folder. I have the code to correlate images. But how to perform this sequentially with the files in the database folder? :frown:

No way to do it in standard C, since you're not required to even have a file system. That said, most common compilers have library functions for working with directories. Look at opendir/readdir/closedir for Unix and GetFirstFile/GetNextFile for Windows.
