| 3835 * It is possible to give a search context from a previous call to | |
| 3836 * vim_findfile_init(), so it can be reused. After this you call vim_findfile() | |
| 3837 * until you are satisfied with the result or it returns NULL. On every call it | |
| 3838 * returns the next file which matches the conditions given to | |
| 3839 * vim_findfile_init(). If it doesn't find a next file it returns NULL. | |
| 3840 * | |
| 3841 * It is possible to call vim_findfile_init() again to reinitialise your search | |
| 3842 * with some new parameters. Don't forget to pass your old search context to | |
| 3843 * it, so it can reuse it and especially reuse the list of already visited | |
| 3844 * directories. If you want to delete the list of already visited directories | |
| 3845 * simply call vim_findfile_free_visited(). | |
