    Read more images at once

    Hi all. How can I read multiple images from a folder, then process them(add some effects) and then redirect them to a specific folder, with a specific name?
        char input[] = "./input/images/file1.bmp";    
        char output[] = "./output/newfile1.bmp";
        FILE *fIn = fopen(input, "rb");
        FILE *fOut = fopen(output, "wb");
        if (!fIn || !fOut)
            printf("File error.\n");
    this is only part of the code. How can I process multiple images at once? From my example, only one image is processed.
    A little help please?

    Accessing command line parameters/arguments
    So for example, you could type
    myprog ./input/images/*.bmp ./output

    Or you could just specify the names of your input and output directories, and use this.
    Accessing a directory and all the files within it
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
