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 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 return OK
Note that all of these routines may be macros.
These functions are described in the XSI Curses standard, Issue 4.
