curs_insch(3x)                                           curs_insch(3x)




NAME

       insch,  winsch,  mvinsch,  mvwinsch  -  insert a character
       before cursor in a curses 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 routines insert the character ch before the  charac-
       ter  under the cursor.  All characters to the right of the
       cursor are moved one space to the right, with  the  possi-
       bility  of the rightmost character on the line being lost.
       The insertion operation does not change the  cursor  posi-
       tion.


RETURN VALUE

       All  routines that return an integer return ERR upon fail-
       ure 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  move-
       ment  using  wmove, and return an error if the position is
       outside the window, or if the window pointer is null.


NOTES

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

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


PORTABILITY

       These  functions are described in the XSI Curses standard,
       Issue 4.
