The following program behaves curiously.
When you run it, the revision date of the file it opens
is updated, if that file is a stream_lf file.
If the file is variable length or fixed length, the
revision date is not updated.

This even occurs when the file protection is (s,o,g,w:r),
and the file is on a directory which is not mine.

Any explanations?

#include        <stdio.h>
main(argc, argv)
        int     argc;
        char    **argv;
        {
        FILE    *inf;
        char    line[BUFSIZ];

        argc--; argv++;
        if ( (inf = fopen(*argv, "r")) != NULL)
                puts("Opened");
        else
                puts("Can't open");
        }
