in_wch, mvin_wch, mvwin_wch, win_wch - extract a complex
character and rendition from a window
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);
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.
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
Note that all of these routines may be macros.
These functions are described in the XSI Curses standard,
