66 If the string is bound to a keycode, its value (greater
67 than zero) is returned. If no keycode is bound, zero is
68 returned. If the string conflicts with longer strings

73 These routines are specific to ncurses. They were not
74 supported on Version 7, BSD or System V implementations.
75 It is recommended that any code depending on them be con-
76 ditioned using NCURSES_VERSION.
