|
|
|
3800 * It is possible to call vim_findfile_init() again to reinitialise your search
|

3801 * with some new parameters. Don't forget to pass your old search context to
|
|

|
|
|
3803 * directories. If you want to delete the list of already visited directories
|
|
|
3804 * simply call vim_findfile_free_visited().
|

3805 *
|
|
|
3806 * When you are done call vim_findfile_cleanup() to free the search context.
