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 rendition from the
current position in the named window into the cchar_t object referenced
No errors are defined in the XSI Curses standard. This implementation
checks for null pointers, returns ERR in that case. Also, the mv rou‐
tines check for error moving the cursor, returning ERR in that case.
Otherwise they return OK
Note that all of these routines may be macros.
These functions are described in the XSI Curses standard, Issue 4.
