DESCRIPTION
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 cursor position does not change after moving to y,
x, if specified. (This does not imply use of the hardware insert-char‐
acter feature.)
NOTES
The header file <curses.h> automatically includes the header file
<stdio.h>.
Note that insch, mvinsch, and mvwinsch may be macros.
RETURN VALUES
All routines return the integer ERR upon failure and OK upon successful
completion.
