For a \fB\s-1UI_METHOD\s0\fR user, there's no need to know more. For a \fB\s-1UI_METHOD\s0\fR creator, it is of interest to fetch text from these \&\fB\s-1UI_STRING\s0\fR objects as well as adding results to some of them. .PP \&\fBUI_get_string_type()\fR is used to retrieve the type of the given \&\fB\s-1UI_STRING\s0\fR. .PP \&\fBUI_get_input_flags()\fR is used to retrieve the flags associated with the given \fB\s-1UI_STRING\s0\fR. .PP \&\fBUI_get0_output_string()\fR is used to retrieve the actual string to output (prompt, info, error, ...). .PP \&\fBUI_get0_action_string()\fR is used to retrieve the action description associated with a \fB\s-1UIT_BOOLEAN\s0\fR type \fB\s-1UI_STRING\s0\fR. For all other \fB\s-1UI_STRING\s0\fR types, \s-1NULL\s0 is returned. See \fBUI_add_input_boolean\fR\|(3). .PP \&\fBUI_get0_result_string()\fR and \fBUI_get_result_string_length()\fR are used to retrieve the result of a prompt and its length. This is only useful for \fB\s-1UIT_PROMPT\s0\fR and \fB\s-1UIT_VERIFY\s0\fR type strings. For all other \fB\s-1UI_STRING\s0\fR types, \fBUI_get0_result_string()\fR returns \s-1NULL\s0 and \fBUI_get_result_string_length()\fR returns \-1. .PP \&\fBUI_get0_test_string()\fR is used to retrieve the string to compare the prompt result with. This is only useful for \fB\s-1UIT_VERIFY\s0\fR type strings. For all other \fB\s-1UI_STRING\s0\fR types, \s-1NULL\s0 is returned. .PP \&\fBUI_get_result_minsize()\fR and \fBUI_get_result_maxsize()\fR are used to retrieve the minimum and maximum required size of the result. This is only useful for \fB\s-1UIT_PROMPT\s0\fR and \fB\s-1UIT_VERIFY\s0\fR type strings. For all other \fB\s-1UI_STRING\s0\fR types, \-1 is returned. .PP \&\fBUI_set_result_ex()\fR is used to set the result value of a prompt and its length. For \fB\s-1UIT_PROMPT\s0\fR and \fB\s-1UIT_VERIFY\s0\fR type \s-1UI\s0 strings, this sets the result retrievable with \fBUI_get0_result_string()\fR by copying the contents of \fBresult\fR if its length fits the minimum and maximum size requirements. For \fB\s-1UIT_BOOLEAN\s0\fR type \s-1UI\s0 strings, this sets the first character of the result retrievable with \fBUI_get0_result_string()\fR to the first \&\fBok_char\fR given with \fBUI_add_input_boolean()\fR or \fBUI_dup_input_boolean()\fR if the \fBresult\fR matched any of them, or the first of the \&\fBcancel_chars\fR if the \fBresult\fR matched any of them, otherwise it's set to the \s-1NUL\s0 char \f(CW\*(C`\e0\*(C'\fR. See \fBUI_add_input_boolean\fR\|(3) for more information on \fBok_chars\fR and \&\fBcancel_chars\fR. .PP \&\fBUI_set_result()\fR does the same thing as \fBUI_set_result_ex()\fR, but calculates its length internally. It expects the string to be terminated with a \s-1NUL\s0 byte, and is therefore only useful with normal C strings. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBUI_get_string_type()\fR returns the \s-1UI\s0 string type. .PP \&\fBUI_get_input_flags()\fR returns the \s-1UI\s0 string flags. .PP \&\fBUI_get0_output_string()\fR returns the \s-1UI\s0 string output string. .PP \&\fBUI_get0_action_string()\fR returns the \s-1UI\s0 string action description string for \fB\s-1UIT_BOOLEAN\s0\fR type \s-1UI\s0 strings, \s-1NULL\s0 for any other type. .PP \&\fBUI_get0_result_string()\fR returns the \s-1UI\s0 string result buffer for \&\fB\s-1UIT_PROMPT\s0\fR and \fB\s-1UIT_VERIFY\s0\fR type \s-1UI\s0 strings, \s-1NULL\s0 for any other type. .PP \&\fBUI_get_result_string_length()\fR returns the \s-1UI\s0 string result buffer's content length for \fB\s-1UIT_PROMPT\s0\fR and \fB\s-1UIT_VERIFY\s0\fR type \s-1UI\s0 strings, \&\-1 for any other type. .PP \&\fBUI_get0_test_string()\fR returns the \s-1UI\s0 string action description string for \fB\s-1UIT_VERIFY\s0\fR type \s-1UI\s0 strings, \s-1NULL\s0 for any other type. .PP \&\fBUI_get_result_minsize()\fR returns the minimum allowed result size for the \s-1UI\s0 string for \fB\s-1UIT_PROMPT\s0\fR and \fB\s-1UIT_VERIFY\s0\fR type strings, \&\-1 for any other type. .PP \&\fBUI_get_result_maxsize()\fR returns the minimum allowed result size for the \s-1UI\s0 string for \fB\s-1UIT_PROMPT\s0\fR and \fB\s-1UIT_VERIFY\s0\fR type strings, \&\-1 for any other type. .PP \&\fBUI_set_result()\fR returns 0 on success or when the \s-1UI\s0 string is of any type other than \fB\s-1UIT_PROMPT\s0\fR, \fB\s-1UIT_VERIFY\s0\fR or \fB\s-1UIT_BOOLEAN\s0\fR, \-1 on error. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\s-1\fBUI\s0\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2001\-2018 The OpenSSL Project Authors.
