get_wstr(3NCURSES)                                          get_wstr(3NCURSES)

       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

       #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);

       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

       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.

       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.

       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.

                   returns an error if the associated call to wget_wch failed.

       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.

       Functions: ncurses(3NCURSES), get_wch(3NCURSES), getstr(3NCURSES).
