curs_get_wstr(3)    UNIX Programmer's Manual	 curs_get_wstr(3)

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 previ-
     ous character (typically 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 series 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 functions,  respectively,  except
     that  the	*n_*  versions read at most n characters, letting
     the application prevent overflow of the input buffer.

NOTES
     Using get_wstr, mvget_wstr,  mvwget_wstr,	or  wget_wstr  to

curs_get_wstr(3)    UNIX Programmer's Manual	 curs_get_wstr(3)

     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, respectively, 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.
     Otherwise, 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  Specifica-
     tion,  Version  2. No error conditions are defined. This im-
     plementation returns ERR if the window pointer is	null,  or
     if	 the  lower-level  wget_wch  call  returns 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.
