NAME

       insch, winsch, mvinsch, mvwinsch - insert a curses character in a window

SYNOPSIS

       #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);

DESCRIPTION

       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.

RETURN VALUE

       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 using wmove and fail if the
       position (y, x) is outside the window.

NOTES

       A terminal's insert_character (ich1) capability is not necessarily employed.

       insch, mvinsch, and mvwinsch may be implemented as macros.

PORTABILITY

       X/Open Curses, Issue 4, describes these functions.

       SVr4 describes successful return values only as “an integer value other than ERR”.

SEE ALSO

       ins_wch(3NCURSES)  describes   comparable   functions   in   the   wide-character   curses
       configuration.
