NAME

       inwstr,  innwstr,  winwstr,  winnwstr,  mvinwstr, mvinnwstr, mvwinwstr, mvwinnwstr - get a
       string of wchar_t characters from a curses window

SYNOPSIS

       #include <curses.h>

       int inwstr(wchar_t *wstr);
       int innwstr(wchar_t *wstr, int n);
       int winwstr(WINDOW *win, wchar_t *wstr);
       int winnwstr(WINDOW *win, wchar_t *wstr, int n);

       int mvinwstr(int y, int x, wchar_t *wstr);
       int mvinnwstr(int y, int x, wchar_t *wstr, int n);
       int mvwinwstr(WINDOW *win, int y, int x, wchar_t *wstr);
       int mvwinnwstr(WINDOW *win, int y, int x, wchar_t *wstr, int n);

DESCRIPTION

       These routines return a string of wchar_t wide characters in wstr, extracted  starting  at
       the current cursor position in the named window.

       The  four  functions  with  n  as  the  last argument return a leading substring at most n
       characters long (exclusive of the trailing NUL).  Transfer stops at the end of the current
       line, or when n characters have been stored at the location referenced by wstr.

       If  the  size  n  is  not  large enough to store a complete complex character, an error is
       generated.

NOTES

       All routines except winnwstr may be macros.

       Each cell in the window holds a complex character (i.e., base-  and  combining-characters)
       together  with  attributes  and  color.   These  functions store only the wide characters,
       ignoring attributes and color.  Use in_wchstr to return  the  complex  characters  from  a
       window.

RETURN VALUE

       All  routines  return  ERR upon failure.  Upon successful completion, the *inwstr routines
       return OK, and the *innwstr routines return the number of characters read into the string.

       Functions with a “mv” prefix first perform a cursor movement using wmove,  and  return  an
       error if the position is outside the window, or if the window pointer is null.
