curs_insch(3X)                                            curs_insch(3X)

NAME         top

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

SYNOPSIS         top

       #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         top

       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 cursor position.

RETURN VALUE         top

       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.

NOTES         top

       These routines do not necessarily imply use of a hardware insert
       character feature.

       Note that insch, mvinsch, and mvwinsch may be macros.

PORTABILITY         top

       These functions are described in the XSI Curses standard, Issue

SEE ALSO         top


       Comparable functions in the wide-character (ncursesw) library are
       described in curs_ins_wch(3X).
