scanw(3cur)scanw(3cur)Name
scanw, mvscanw, mvwscanw, wscanw - formatted read from window
Syntax
#include <cursesX.h>
int scanw(fmt [, arg] ...)
char *fmt;
int wscanw(win, fmt [, arg] ...)
WINDOW *win;
char *fmt;
int mvscanw(y, x, fmt [, arg] ...)
int y, x;
char *fmt;
int mvwscanw(win, y, x, fmt [, arg] ...)
WINDOW *win;
int y, x;
char *fmt;
Description
These routines correspond to The function reads input from the default window. The function reads input from the specified window. The
function moves the cursor to the specified position and then reads input from the default window. The function moves the cursor to the
specified position and then reads input from the specified window.
For all the functions, the routine is called to get a string from the window, and the resulting line is used as input for the scan. All
character interpretation is carried out according to the function rules.
Return Values
Upon successful completion, the and functions return the number of items successfully matched. On end-of-file, they return EOF. Otherwise
they return ERR.

curs_scanw(3CURSES) Curses Library Functions curs_scanw(3CURSES)NAME
curs_scanw, scanw, wscanw, mvscanw, mvwscanw, vwscanw - convert formatted input from a curses widow
SYNOPSIS
cc [ flag ... ] file ... -lcurses [ library ... ]
#include <curses.h>
int scanw(char *fmt, /* arg */ ...);
int wscanw(WINDOW *win, char *fmt, /* arg */ ...);
int mvscanw(int y, int x, char *fmt, /* arg */ ...);
int mvwscanw(WINDOW *win, int y, int x, char *fmt, /* arg */...);
int vwscanw(WINDOW *win, char *fmt, va_list varglist);
DESCRIPTION
The scanw(), wscanw(), and mvscanw() routines correspond to scanf() (see scanf(3C)). The effect of these routines is as though wgetstr()
were called on the window, and the resulting line used as input for the scan. Fields which do not map to a variable in the fmt field are
lost.
The vwscanw() routine is similar to vwprintw() in that it performs a wscanw() using a variable argument list. The third argument is a
va_list, a pointer to a list of arguments, as defined in <varargs.h>.
RETURN VALUES
vwscanw() returns ERR on failure and an integer equal to the number of fields scanned on success.
Applications may interrogate the return value from the scanw, wscanw(), mvscanw(), and mvwscanw() routines to determine the number of
fields which were mapped in the call.

I'm writing a command shell, and I want to be able to detect when the user presses an arrow key (otherwise it just prints [[A, [[B, etc.).
