Try perror() for a better description of the error.

if (!outfile) {
    /* printf("There was a problem opening %s for writing\n", outname); */
    perror(outname);
}

Use access, see eg [this SO question and answers](http://stackoverflow.com/questions/230062/whats-the-best-way-to-check-if-a-file-exists-in-c-cross-platform). – pmg Sep 20 '12 at 17:16
