NCURSES keypad

hi

Please tell me that in NCURSES when i use function
keypad(), i can use KEY_UP,KEY_DOWN,KEYF0..and so on.

values of these macros are there in ncurses.h.

now my problem is that, when i press a key and match corresponding ascii value from ncurses.h, it does not match.
for eg. KEY_UP has the value 403 in ncurses.h
but i get the value 259
similarly KEY_DOWN has the value 402 in ncurses.h
but i get the value 258..

i dont understand the matter

all suggestions are welcome

In ncurses.h I have something like that:

Code:

#define KEY_UP       0403

0403 is an octal number, not decimal (you have 0 before the number). So octal 403 is decimal 259 (4*8^2+3).

Normally you shouldn't worry about the numeric value of the keystroke. If you need to check for it check for key == KEY_UP, not key == 259
