position in the named window into the cchar_t object referenced by
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.
int mvwin_wch(WINDOW *win, int y, int
x , cchar_t *wcval);
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.
Note that all of these routines may be macros.
These functions are described in the XSI Curses standard, Issue 4.
