curs_delch(3X)			 Library calls			curs_delch(3X)

NAME
       delch,  wdelch,	mvdelch,  mvwdelch  - delete a character from 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
       wdelch  deletes	the  character	at  the	 cursor	  position   in	  win.
       ncurses(3X) describes the variants of this function.

       wdelch moves all	characters to the right	of the cursor on the same line
       to the left one position	and replaces the contents of the rightmost po-
       sition  on  the	line  with  the	window's blank character; see bkgd(3X)
       (wide-character API users may consult bkgrnd(3X)	instead).  The	cursor
       position	does not change	(after moving to (y, x), if specified).

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

NOTES
       delch, mvdelch, and mvwdelch may	be implemented as macros.

       A terminal's delete_character (dch1) capability is not necessarily  em-
       ployed.

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

       SVr4  curses  describes	a  successful return value only	as "an integer
       value other than	ERR".
