through calls to UI_add_user_data() or UI_dup_user_data(). The default
UI method doesn't care about these data, but other methods might. Finally,
use UI_process() to actually perform the prompting and UI_get0_result()
-to find the result to the prompt.
+and UI_get_result_length() to find the result to the prompt and its length.
A UI can contain more than one prompt, which are performed in the given
sequence. Each prompt gets an index number which is returned by the
UI_add and UI_dup functions, and has to be used to get the corresponding
-result with UI_get0_result().
+result with UI_get0_result() and UI_get_result_length().
UI_process() can be called more than once on the same UI, thereby allowing
a UI to have a long lifetime, but can just as well have a short lifetime.
UI_new_method() creates a new UI using the given UI method. When done with
this UI, it should be freed using UI_free().

+UI_OpenSSL() returns the built-in UI method (note: not necessarily the
default one, since the default can be changed. See further on). This
method is the most machine/OS dependent part of OpenSSL and normally
generates the most problems when porting.

the information indexed by I<i>.

UI_process() goes through the information given so far, does all the printing
and prompting and returns the final status, which is -2 on out-of-band events
(Interrupt, Cancel, ...), -1 on error and 0 on success.
