|
|
|
3709 * It is possible to give a search context from a previous call to

3710 * vim_findfile_init(), so it can be reused. After this you call vim_findfile()
|
|
|
3711 * until you are satisfied with the result or it returns NULL. On every call it
|
|
|
3712 * returns the next file which matches the conditions given to
|
|
|
3713 * vim_findfile_init(). If it doesn't find a next file it returns NULL.
|
|
|
3714 *
|
|
|
3715 * It is possible to call vim_findfile_init() again to reinitialise your search
|
|
|
3716 * with some new parameters. Don't forget to pass your old search context to
|
|
|
3717 * it, so it can reuse it and especially reuse the list of already visited
|
|
|
3718 * directories. If you want to delete the list of already visited directories
|
|
|
3719 * simply call vim_findfile_free_visited().
|
|
|
3720 *
|
|
|
3721 * When you are done call vim_findfile_cleanup() to free the search context.
|
|
|

|

3723 * The function vim_findfile_init() has a long comment, which describes the
