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 rendition 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 cur-
       sor, returning ERR in that case.  Otherwise they return OK

       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.

NOTES
       Note that all of these routines may be macros.

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