A UI_STRING gets created internally and added to a UI object whenever one of the functions UI_add_input_string(3), UI_dup_input_string(3), UI_add_verify_string(3), UI_dup_verify_string(3), UI_add_input_boolean(3), UI_dup_input_boolean(3), UI_add_info_string(3), UI_dup_info_string(3), UI_add_error_string(3) or UI_dup_error_string(3) is called. For a UI_METHOD user, there's no need to know more. For a UI_METHOD creator, it is of interest to fetch text from these UI_STRING objects as well as adding results to some of them.

() is used to retrieve the type of the given UI_STRING.

() is used to retrieve the flags associated with the given UI_STRING.

() is used to retrieve the actual string to output (prompt, info, error, ...).

() is used to retrieve the action description associated with a UIT_BOOLEAN type UI_STRING. See UI_add_input_boolean(3).

() is used to retrieve the result of a prompt. This is only useful for UIT_PROMPT and UIT_VERIFY type strings.

() is used to retrieve the string to compare the prompt result with. This is only useful for UIT_VERIFY type strings.

() and () are used to retrieve the minimum and maximum required size of the result. This is only useful for UIT_PROMPT and UIT_VERIFY type strings.

() is used to set the result value of a prompt. For and type UI strings, this sets the result retrievable with UI_get0_result_string() by copying the contents of result if its length fits the minimum and maximum size requirements. For UIT_BOOLEAN type UI strings, this sets the first character of the result retrievable with UI_get0_result_string() to the first of the ok_chars given with UI_add_input_boolean(3) or UI_dup_input_boolean(3) if the result matched any of them, or the first of the cancel_chars if the result matched any of them, otherwise it's set to the NUL char. See UI_add_input_boolean(3) for more information on ok_chars and cancel_chars.

UI_get_string_type() returns the UI string type.

UI_get_input_flags() returns the UI string flags.

UI_get0_output_string() returns the UI string output string.

UI_get0_action_string() returns the UI string action description string for UIT_BOOLEAN type UI strings, or NULL for any other type.

UI_get0_result_string() returns the UI string result buffer for UIT_PROMPT and UIT_VERIFY type UI strings, or NULL for any other type.

UI_get0_test_string() returns the UI string action description string for UIT_VERIFY type UI strings, or NULL for any other type.

UI_get_result_minsize() returns the minimum allowed result size for the UI string for UIT_PROMPT and UIT_VERIFY type strings, or -1 for any other type.

UI_get_result_maxsize() returns the minimum allowed result size for the UI string for UIT_PROMPT and UIT_VERIFY type strings, or -1 for any other type.

UI_set_result() returns 0 on success or when the UI string is of any type other than UIT_PROMPT, UIT_VERIFY, or UIT_BOOLEAN, or -1 on error.
