curs_scanw(3X)   MISCELLANEOUS LIBRARY FUNCTIONS   curs_scanw(3X)



NAME
     cursscanw:  scanw, wscanw,  mvscanw,  mvwscanw,  vwscanw  -
     convert formatted input from a curses widow

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

DESCRIPTION
     The scanw, wscanw and mvscanw routines correspond  to  scanf
     [see  scanf(3S)].  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 VALUE
     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.

NOTES
     The header file <curses.h> automatically includes the header
     files <stdio.h> and <unctrl.h>.
