| 3749 * vim_findfile_init(), so it can be reused. After this you call vim_findfile() | |

| 3752 * vim_findfile_init(). If it doesn't find a next file it returns NULL. | |
| 3753 * | |
| 3754 * It is possible to call vim_findfile_init() again to reinitialise your search | |
| 3755 * with some new parameters. Don't forget to pass your old search context to | |
| 3756 * it, so it can reuse it and especially reuse the list of already visited | |
| 3757 * directories. If you want to delete the list of already visited directories | |
| 3758 * simply call vim_findfile_free_visited(). | |
