CURSES_SCANW(3)         NetBSD Library Functions Manual        CURSES_SCANW(3)


NAME

     curses_scanw, scanw, wscanw, mvscanw, mvwscanw -- curses read formatted
     data from screen routines


LIBRARY

     Curses Library (libcurses, -lcurses)


SYNOPSIS

     #include <curses.h>

     int
     scanw(const char *fmt, ...);

     int
     wscanw(WINDOW *win, const char *fmt, ...);

     int
     mvscanw(int y, int x, const char *fmt, ...);

     int
     mvwscanw(WINDOW *win, int y, int x, const char *fmt, ...);


DESCRIPTION

     These functions read formatted data from stdscr or from the specified
     window.

     The scanw() function is the same as the scanf() function, excepting that
     the input data stream is read from the current cursor position on stdscr,

     The wscanw() function is the same as the scanw() function, excepting that
     the data stream is read from the window specified by win.

     The mvscanw() and mvwscanw() functions are the same as the scanw() and
     mvscanw() functions, respectively, excepting that wmove() is called to
     move the cursor to the position specified by y, x before the data is read
     from the window.


RETURN VALUES

     Functions returning pointers will return NULL if an error is detected.
     The functions that return an int will return one of the following values:

     OK   The function completed successfully.
     ERR  An error occurred in the function.


SEE ALSO
