curs_delch(3x)                                                  curs_delch(3x)




NAME

       delch, wdelch, mvdelch, mvwdelch - delete character under the cursor in
       a curses window


SYNOPSIS

       #include <curses.h>

       int delch(void);
       int wdelch(WINDOW *win);
       int mvdelch(int y, int x);
       int mvwdelch(WINDOW *win, int y, int x);


DESCRIPTION

       These routines delete the character under the cursor; all characters to
       the  right  of  the  cursor  on the same line are moved to the left one
       position and the last character on the line is  filled  with  a  blank.
       The  cursor  position  does  not  change  (after  moving  to  y,  x, if
       specified).  (This does not imply use of the hardware delete  character
       feature.)


RETURN VALUE

       All  routines  return  the  integer  ERR  upon  failure and an OK (SVr4
       specifies only "an integer  value  other  than  ERR")  upon  successful
       completion.

       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

       Note that delch, mvdelch, and mvwdelch may be macros.


PORTABILITY

       These functions are described in the XSI Curses standard, Issue 4.  The
       standard specifies that they return ERR on failure,  but  specifies  no
       error conditions.
