=head1 SYNOPSIS
int verify);
int UI_UTIL_read_pw(char *buf, char *buff, int size, const char *prompt,
int verify);
- UI_METHOD *UI_UTIL_wrap_read_pem_callback(pem_password_cb *cb, int
- rwflag);
+ UI_METHOD *UI_UTIL_wrap_read_pem_callback(pem_password_cb *cb, int rwflag);
=head1 DESCRIPTION
When not used any more, the returned method should be freed with
UI_destroy_method().
+=head1 NOTES
+
+UI_UTIL_read_pw_string() and UI_UTIL_read_pw() use default
+B<UI_METHOD>.
+See L<UI_get_default_method(3)> and friends for more information.
+
+The result from the B<UI_METHOD> created by
+UI_UTIL_wrap_read_pem_callback() will generate password strings in the
+encoding that the given password callback generates.
+The default password prompting functions (apart from
+UI_UTIL_read_pw_string() and UI_UTIL_read_pw(), there is
+PEM_def_callback(), EVP_read_pw_string() and EVP_read_pw_string_min())
+all use the default B<UI_METHOD>.
+
+=head1 RETURN VALUES
+
+UI_UTIL_read_pw_string() and UI_UTIL_read_pw() return 0 on success or a negative
+value on error.
+
+UI_UTIL_wrap_read_pem_callback() returns a valid B<UI_METHOD> structure or NULL
+if an error occurred.
