|
|
|
3578 * In general it works like this:
|
|
|
3579 * First you create yourself a search context by calling vim_findfile_init().
|
|
|
3580 * It is possible to give a search context from a previous call to
|
|
|
3581 * vim_findfile_init(), so it can be reused. After this you call vim_findfile()
|
|
|
3582 * until you are satisfied with the result or it returns NULL. On every call it
|
|
|
3583 * returns the next file which matches the conditions given to
|
|
|
3584 * vim_findfile_init(). If it doesn't find a next file it returns NULL.
|
|
|
3585 *
|
|
|
3586 * It is possible to call vim_findfile_init() again to reinitialise your search
|
|
|
3587 * with some new parameters. Don't forget to pass your old search context to
|
|
|
3588 * it, so it can reuse it and especially reuse the list of already visited
|
|
|
3589 * directories. If you want to delete the list of already visited directories
|
|
|
3590 * simply call vim_findfile_free_visited().
|
|
|
3591 *
|
|
|
3592 * When you are done call vim_findfile_cleanup() to free the search context.
|
|
|
3593 *
|
|
|
3594 * The function vim_findfile_init() has a long comment, which describes the
|
|
|
3595 * needed parameters.

5594 * associate a value longer than the current value with a particular

5595 * name. So, to make life simpler, putenv() copies your entire
