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
       cursor, 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.
