    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 fea-
           ture.)

## 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  move-
           ment  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.
