3779 * First you create yourself a search context by calling vim_findfile_init().
|
|
3780 * It is possible to give a search context from a previous call to
|
|
3781 * vim_findfile_init(), so it can be reused. After this you call vim_findfile()
|

3782 * until you are satisfied with the result or it returns NULL. On every call it

3783 * returns the next file which matches the conditions given to
|
|
3784 * vim_findfile_init(). If it doesn't find a next file it returns NULL.
|
|
3785 *
|
|
3786 * It is possible to call vim_findfile_init() again to reinitialise your search
|
|
3787 * with some new parameters. Don't forget to pass your old search context to
|
|
3788 * it, so it can reuse it and especially reuse the list of already visited
|
|
3789 * directories. If you want to delete the list of already visited directories
|
|
3790 * simply call vim_findfile_free_visited().
|
|
3791 *
|
|
3792 * When you are done call vim_findfile_cleanup() to free the search context.

|
3793 *
