SYNOPSIS

        int delch(void);

-       int mvdelch(int y, int x);
-       int mvwdelch(WINDOW *win, 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.)
+

DESCRIPTION

+       wdelch deletes the character at the cursor position in win.   It  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 position on the
+       line  with  the  window's blank character; see bkgd(3x) (wide-character
+       API users: bkgrnd(3x)).  The cursor position  does  not  change  (after
+       moving to (y, x), if specified).  ncurses(3x) describes the variants of
+       this function.

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.
+

RETURN VALUE

+       These functions return OK on success and ERR on failure.
 
-       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.
+       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

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

NOTES

+       delch, mvdelch, and mvwdelch may be implemented as 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.
+       A  terminal's  delete_character  (dch1)  capability  is not necessarily
+       employed.

PORTABILITY

+       X/Open Curses, Issue 4 describes  these  functions.   It  specifies  no
+       error conditions for them.
+
+       SVr4  curses  describes  a  successful return value only as "an integer
+       value other than ERR".
