curs_get_wstr(3X)					     curs_get_wstr(3X)

NAME
       get_wstr, getn_wstr, wget_wstr, wgetn_wstr, mvget_wstr, mvgetn_wstr,
       mvwget_wstr, mvwgetn_wstr - get an array	of wide	characters from	a
       curses terminal keyboard

SYNOPSIS
       #include	<curses.h>

       int get_wstr(wint_t *wstr);
       int getn_wstr(wint_t *wstr, int n);
       int wget_wstr(WINDOW *win, wint_t *wstr);
       int wgetn_wstr(WINDOW *win, wint_t *wstr, int n);
       int mvget_wstr(int y, int x, wint_t *wstr);
       int mvgetn_wstr(int y, int x, wint_t *wstr, int n);
       int mvwget_wstr(WINDOW *win, int	y, int x, wint_t *wstr);
       int mvwgetn_wstr(WINDOW *win, int y, int	x, wint_t *wstr, int n);

DESCRIPTION
       The  effect  of get_wstr	is as though a series of calls to get_wch were
       made, until a newline, other end-of-line, or end-of-file	 condition  is
       processed.  An end-of-file condition is represented by WEOF, as defined
       in <wchar.h>.  The newline and end-of-line conditions  are  represented
       by  the	\n  wchar_t value.  In all instances, the end of the string is
       terminated by a null wchar_t.  The routine places resulting  values  in
       the area	pointed	to by wstr.

       The  user's  erase and kill characters are interpreted.	If keypad mode
       is on for the window, KEY_LEFT and KEY_BACKSPACE	 are  both  considered
       equivalent to the user's	kill character.

       Characters  input  are  echoed  only  if	echo is	currently on.  In that
       case, backspace is echoed as deletion of	the previous character	(typi-
       cally a left motion).

       The effect of wget_wstr is as though a series of	calls to wget_wch were
       made.

       The effect of mvget_wstr	is as though a call to move and	then a	series
       of calls	to get_wch were	made.

       The  effect  of mvwget_wstr is as though	a call to wmove	and then a se-
       ries of calls to	wget_wch were made.

       The getn_wstr, mvgetn_wstr, mvwgetn_wstr, and wgetn_wstr	functions  are
       identical to the	get_wstr, mvget_wstr, mvwget_wstr, and wget_wstr func-
       tions, respectively, except that	the *n_* versions read at most n char-
       acters, letting the application prevent overflow	of the input buffer.

NOTES
       Using  get_wstr,	 mvget_wstr,  mvwget_wstr, or wget_wstr	to read	a line
       that overflows the array	pointed	to by wstr causes  undefined  results.
       The use of getn_wstr, mvgetn_wstr, mvwgetn_wstr,	or wgetn_wstr, respec-
       tively, is recommended.

       These functions cannot return KEY_ values because there is  no  way  to
       distinguish a KEY_ value	from a valid wchar_t value.

       All of these routines except wgetn_wstr may be macros.

RETURN VALUES
       All  of	these  functions return	OK upon	successful completion.	Other-
       wise, they return ERR.

       Functions using a window	parameter return an error if it	is null.

	      wgetn_wstr
		   returns an error if the associated call to wget_wch failed.

PORTABILITY
       These functions are described in	The Single Unix	Specification, Version
       2.  No error conditions are defined.  This implementation  returns  ERR
       if  the window pointer is null, or if the lower-level wget_wch call re-
       turns an	ERR.  In the latter case, an ERR return	without	other data  is
       treated	as an end-of-file condition, and the returned array contains a
       WEOF followed by	a null wchar_t.

       X/Open curses documents these functions to pass an  array  of  wchar_t,
       but all of the vendors implement	this using wint_t.
