curs_insch(3x)                   Library calls                  curs_insch(3x)
       insch,  winsch,  mvinsch,  mvwinsch  -  insert  a curses character in a
       window
       #include <curses.h>
       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 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".
       curs_ins_wch(3x) describes comparable functions in  the  wide-character
       curses configuration.
