Additionally, the verify addition - functions takes another buffer to compare the result against. - The boolean input functions take an action description string (which should - be safe to ignore if the expected user action is obvious, for example with - a dialog box with an OK button and a Cancel button), a string of acceptable - characters to mean OK and to mean Cancel. The two last strings are checked - to make sure they don't have common characters. Additionally, the same - flag argument as for the string input is taken, as well as a result buffer. - The result buffer is required to be at least one byte long. Depending on - the answer, the first character from the OK or the Cancel character strings - will be stored in the first byte of the result buffer.

It can be used to actually - display a dialog box after it has been built. - a reader This function is called to read a given prompt, - maybe from the tty, maybe from a field in a - window.
