|
|
3741 * First you create yourself a search context by calling vim_findfile_init().
|
|
3742 * It is possible to give a search context from a previous call to
|
|
3743 * vim_findfile_init(), so it can be reused. After this you call vim_findfile()
|
|
3744 * until you are satisfied with the result or it returns NULL. On every call it
|
|
3745 * returns the next file which matches the conditions given to
|
|
3746 * vim_findfile_init(). If it doesn't find a next file it returns NULL.
|
|
3747 *
|
|
3748 * It is possible to call vim_findfile_init() again to reinitialise your search
|
|
3749 * with some new parameters. Don't forget to pass your old search context to
|
|
3750 * it, so it can reuse it and especially reuse the list of already visited
|
|
3751 * directories. If you want to delete the list of already visited directories
|
|
3752 * simply call vim_findfile_free_visited().
|
|
3753 *
|
|
3754 * When you are done call vim_findfile_cleanup() to free the search context.
|
|
3755 *
|

3756 * The function vim_findfile_init() has a long comment, which describes the

3757 * needed parameters.
