wins_wch3ncurses
Insert a curses complex character in a window
Part of ins_wch(3ncurses).
Overview
These functions insert the curses complex character wch 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.
Return value
These functions return OK on success and ERR on failure.
Functions taking a WINDOW pointer argument fail if win is a null pointer.
Functions prefixed with “mv” first perform cursor movement and fail if the position (y, x) is outside the window boundaries.
Notes
ins_wch, mvins_wch, and mvwins_wch may be implemented as macros.
A terminal's insert_character (ich1) capability is not necessarily employed.
Portability
X/Open Curses Issue 4 describes these functions. It specifies no error conditions for them.
