NAME

curs_scanw, scanw, wscanw, mvscanw, mvwscanw, vw_scanw, vwscanw - Convert formatted input from a Curses window  

SYNOPSIS

#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]... ); include <stdarg.h> include <curses.h>

int vw_scanw( WINDOW *win, char *fmt, va_list varglist ); include <varargs.h> include <curses.h>

int vwscanw( WINDOW *win, char *fmt, va_list varglist );
 

LIBRARY

Curses Library (libcurses)
 

STANDARDS

Interfaces documented on this reference page conform to industry standards as follows:

scanw, wscanw, mvscanw, mvwscanw, vw_scanw, vwscanw:  XPG4-UNIX

Refer to the standards(5) reference page for more information about industry standards and associated tags.
 

DESCRIPTION

The scanw, wscanw, and mvscanw routines correspond to scanf (see fscanf(3)). The effect of these routines is as though wgetstr were called on the window, and the resulting line were used as input for the scan. Fields that do not map to a variable in the fmt field are lost.

The vw_scanw routine is similar to vwprintw in that it uses a variable argument list. The third argument is va_list, a pointer to a list of arguments, as defined in <stdarg.h>.

The vwscanw routine is equivalent to vw_scanw except that va_list is defined in <varargs.h>. Use of vw_scanw is recommended for new applications.
 

NOTES

The header file <curses.h> automatically includes the header file <stdio.h>.
 

RETURN VALUES

These routines return ERR on failure and OK upon successful completion.
