3863 * All static functions and variables start with 'ff_' | |
3864 * | |
3865 * In general it works like this: | |
3866 * First you create yourself a search context by calling vim_findfile_init(). | |
3867 * It is possible to give a search context from a previous call to | |
3868 * vim_findfile_init(), so it can be reused. After this you call vim_findfile() | |
3869 * until you are satisfied with the result or it returns NULL. On every call it | |
3870 * returns the next file which matches the conditions given to | |
3871 * vim_findfile_init(). If it doesn't find a next file it returns NULL. | |
3872 * | |
3873 * It is possible to call vim_findfile_init() again to reinitialise your search | |
3874 * with some new parameters. Don't forget to pass your old search context to | |
3875 * it, so it can reuse it and especially reuse the list of already visited | |
3876 * directories. If you want to delete the list of already visited directories | |
3877 * simply call vim_findfile_free_visited(). | |
3878 * | |
3879 * When you are done call vim_findfile_cleanup() to free the search context. | |

3881 * The function vim_findfile_init() has a long comment, which describes the | |

7 | 3889 * thread-safe!!!!! |
3890 * | |
3891 * To minimize parameter passing (or because I'm to lazy), only the | |
