+ These functions insert the curses character ch at the cursor in the + specified window win (or stdscr). The character previously at the + cursor and any to its right move one cell to the right; the rightmost + character on the line is discarded. The cursor does not advance. +
+ These functions return OK on success and ERR on failure. + Functions taking a WINDOW pointer argument fail if the pointer is NULL. + Functions prefixed with "mv" first perform cursor movement and fail if + the position (y, x) is outside the window boundaries. +
+ insch, mvinsch, and mvwinsch may be implemented as macros. + A terminal's insert_character (ich1) capability is not necessarily + employed. +
+ X/Open Curses, Issue 4 describes these functions. + SVr4 curses describes a successful return value only as "an integer + value other than ERR". +
