3592 *
|
|
|
3593 * In general it works like this:
|
|
|
3594 * First you create yourself a search context by calling vim_findfile_init().
|
|
|
3595 * It is possible to give a search context from a previous call to
|
|
|
3596 * vim_findfile_init(), so it can be reused. After this you call vim_findfile()
|
|
|
3597 * until you are satisfied with the result or it returns NULL. On every call it
|
|
|
3598 * returns the next file which matches the conditions given to
|
|
|
3599 * vim_findfile_init(). If it doesn't find a next file it returns NULL.
|
|
|
3600 *
|
|
|
3601 * It is possible to call vim_findfile_init() again to reinitialise your search
|
|
|
3602 * with some new parameters. Don't forget to pass your old search context to
|
|
|
3603 * it, so it can reuse it and especially reuse the list of already visited
|
|
|
3604 * directories. If you want to delete the list of already visited directories
|
|
|
3605 * simply call vim_findfile_free_visited().
|
|
|
3606 *
|
|
|
3607 * When you are done call vim_findfile_cleanup() to free the search context.
|
|
|
3608 *
|
|
|
3609 * The function vim_findfile_init() has a long comment, which describes the
|
|
|
3610 * needed parameters.
