3548 * vim_findfile_init() creates/initialises the search context
|
|
|
3549 * vim_findfile_free_visited() free list of visited files/dirs of search

3550 * context
|

3551 * vim_findfile() find a file in the search context

|
|
|
3555 * All static functions and variables start with 'ff_'
|
|
|
3556 *
|
|
|
3557 * In general it works like this:
|
|
|
3558 * First you create yourself a search context by calling vim_findfile_init().
|
|
|
3559 * It is possible to give a search context from a previous call to
|
|
|
3560 * vim_findfile_init(), so it can be reused. After this you call vim_findfile()
|
|
|
3561 * until you are satisfied with the result or it returns NULL. On every call it
|
|
|
3562 * returns the next file which matches the conditions given to
|
|
|
3563 * vim_findfile_init(). If it doesn't find a next file it returns NULL.
|
|
|
3564 *
|
|
|
3565 * It is possible to call vim_findfile_init() again to reinitialise your search
|
|
|
3566 * with some new parameters. Don't forget to pass your old search context to
|
|
|
3567 * it, so it can reuse it and especially reuse the list of already visited
|
|
|
3568 * directories. If you want to delete the list of already visited directories
|
|
|
3569 * simply call vim_findfile_free_visited().
|
|
|
3570 *
|
|
|
3571 * When you are done call vim_findfile_cleanup() to free the search context.
|
|
|
3572 *
|
|
|
3573 * The function vim_findfile_init() has a long comment, which describes the
|
|
|
3574 * needed parameters.
