curs_get_wstr 3x


       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 condi-
       tion 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  pre-
       vious 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.


       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, respectively, is

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

       All of these routines except wgetn_wstr may be macros.


       All of these functions return OK upon  successful  comple-
       tion.  Otherwise, they return ERR.


       These  functions are described in The Single Unix Specifi-
       cation, 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 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.


       Functions:  curses(3x), curs_get_wch(3x), curs_getstr(3x).
