| 3739 * External visible functions: | |
| 3740 * vim_findfile_init() creates/initialises the search context | |
| 3741 * vim_findfile_free_visited() free list of visited files/dirs of search | |
| 3742 * context | |

| 3744 * vim_findfile_cleanup() cleanup/free search context created by | |

| 3746 * | |
| 3747 * All static functions and variables start with 'ff_' | |
| 3748 * | |
| 3749 * In general it works like this: | |
| 3750 * First you create yourself a search context by calling vim_findfile_init(). | |
| 3751 * It is possible to give a search context from a previous call to | |
| 3752 * vim_findfile_init(), so it can be reused. After this you call vim_findfile() | |
| 3753 * until you are satisfied with the result or it returns NULL. On every call it | |
| 3754 * returns the next file which matches the conditions given to | |
| 3755 * vim_findfile_init(). If it doesn't find a next file it returns NULL. | |
| 3756 * | |
| 3757 * It is possible to call vim_findfile_init() again to reinitialise your search | |
| 3758 * with some new parameters. Don't forget to pass your old search context to | |
| 3759 * it, so it can reuse it and especially reuse the list of already visited | |
| 3760 * directories. If you want to delete the list of already visited directories | |
| 3761 * simply call vim_findfile_free_visited(). | |
| 3762 * | |
| 3763 * When you are done call vim_findfile_cleanup() to free the search context. | |
| 3764 * | |

| 3766 * needed parameters. | |

| 3776 * external visible functions get a search context as a parameter. This is | |
