Function delete_in_dir

generator.c:279–354

This function is used to implement per-directory deletion, and is used by * all the --delete-WHEN options. Note that the fbuf pointer must point to a * MAXPATHLEN buffer with the name of the directory in it (the functions we * call will append names onto the end, but the old dir value will be restored * on exit). */
