STANDARDS    [Toc]    [Back]

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

       scanw,   wscanw,   mvscanw,   mvwscanw,   vw_scanw,   vwscanw:
  XCURSES4.2

DESCRIPTION    [Toc]    [Back]

       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    [Toc]    [Back]

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

RETURN VALUES    [Toc]    [Back]

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