mvscanw(), mvwscanw(), scanw(), vwscanw(), wscanw()

convert formatted input from a curses widow 

Curses Function


#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);


The scanw(), wscanw() and mvscanw() routines are analogous to scanf(). The effect of these routines is as though wgetstr() were called on the window, and the resulting line used as input for sscanf(). 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>.


vwscanw() returns ERR on failure and an integer equal to the number of fields scanned on success.

Applications may use the return value from the scanw(), wscanw(), mvscanw() and mvwscanw() routines to determine the number of fields which were mapped in the call.


The XSI Curses standard, Issue 4 describes these functions. The function vwscanw() is marked TO BE WITHDRAWN, and is to be replaced by a function vw_scanw() using the <stdarg.h> interface.
