NAME

       in_wch,  mvin_wch,  mvwin_wch, win_wch - extract a complex
       character and rendition from a window


SYNOPSIS

       #include <curses.h>

       int in_wch(cchar_t *wcval);
       int mvin_wch(int y, int x, cchar_t *wcval);
       int mvwin_wch(WINDOW *win, int y, int x, cchar_t *wcval);
       int win_wch(WINDOW *win, cchar_t *wcval);


DESCRIPTION

       These functions extract the complex character  and  rendi-
       tion  from  the  current position in the named window into
       the cchar_t object referenced by wcval.


RETURN VALUE

       No errors are defined in the XSI  Curses  standard.   This
       implementation  checks  for  null pointers, returns ERR in
       that case.  Also, the mv routines check for  error  moving
       the  cursor,  returning  ERR in that case.  Otherwise they
       return OK

       Functions with a "mv" prefix first perform a cursor  move-
       ment  using  wmove, and return an error if the position is
       outside the window, or if the window pointer is null.


NOTES

       Note that all of these routines may be macros.


PORTABILITY

       These functions are described in the XSI Curses  standard,
       Issue 4.
