| 3825 * It is possible to give a search context from a previous call to | |
| 3826 * vim_findfile_init(), so it can be reused. After this you call vim_findfile() | |
| 3827 * until you are satisfied with the result or it returns NULL. On every call it | |
| 3828 * returns the next file which matches the conditions given to | |
| 3829 * vim_findfile_init(). If it doesn't find a next file it returns NULL. | |
| 3830 * | |
| 3831 * It is possible to call vim_findfile_init() again to reinitialise your search | |
| 3832 * with some new parameters. Don't forget to pass your old search context to | |
| 3833 * it, so it can reuse it and especially reuse the list of already visited | |
| 3834 * directories. If you want to delete the list of already visited directories | |
| 3835 * simply call vim_findfile_free_visited(). | |
