RETURN VALUE These functions all return TRUE or FALSE, except as noted. NOTES Both a macro and a function are provided for each name. PORTABILITY These routines are specific to ncurses. They were not supported on Version 7, BSD or System V implementations. It is recommended that any code depending on ncurses extensions be conditioned using NCURSES_VER- SION.
