insch, mvinsch, mvwinsch, winsch - insert character
int winsch(win, ch)
int mvinsch(y, x, ch)
int y, x;
int mvwinsch(win, y, x, ch)
int y, x;
The routine inserts the character at the current cursor position on the default window.
The routine inserts the character at the specified cursor position on the default window.
The routine inserts the character at the current cursor position on the specified window.
The routine inserts the character at the specified cursor position on the specified window.
All the routines cause the following actions. All characters from the cursor position to the right edge are moved one space to the right.
The last character on the line is always lost, even if it is a blank. The cursor position does not change after the insert is completed.
The and routines are macros.
The and functions return OK on success and ERR on error.

insch, winsch, mvinsch, mvwinsch - insert a character before cursor in a curses window
int insch(chtype ch);
int winsch(WINDOW *win, chtype ch);
int mvinsch(int y, int x, chtype ch);
int mvwinsch(WINDOW *win, int y, int x, chtype ch);
These routines insert the character ch before the character under the cursor. All characters to the right of the cursor are moved one
space to the right, with the possibility of the rightmost character on the line being lost. The insertion operation does not change the
All routines that return an integer return ERR upon failure and OK (SVr4 specifies only "an integer value other than ERR") upon successful
completion, unless otherwise noted in the preceding routine descriptions.
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.
These routines do not necessarily imply use of a hardware insert character feature.
Note that insch, mvinsch, and mvwinsch may be macros.
These functions are described in the XSI Curses standard, Issue 4.

We have quite a few threads about this subject. I have collected some of them and arranged them by the OS which is primarily discussed in the thread.

I'm writing a command shell, and I want to be able to detect when the user presses an arrow key (otherwise it just prints [[A, [[B, etc.). I know it's relatively easy (although somewhat more time-consuming) to detect keystrokes in noncanonical mode, but I've noticed that the bash shell detects... (4 Replies)
I'm learning off Linux (Ubuntu) right now. I want to move up to Unix, but I don't want to rush like I did when it came to Windows --> to Linux. What is the best Unix OS that fits in pretty well with Ubuntu.
In other words is there kind of an equal Linux with Unix?
Also what do I need to... (10 Replies)
