+       delch,  wdelch,  mvdelch,  mvwdelch  - delete a character from a curses
+       window

SYNOPSIS

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.)
+       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.
+       These functions return OK on success and ERR on failure.
 
-       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.
+       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.
+       delch, mvdelch, and mvwdelch may be implemented as macros.
+
+       A  terminal's  delete_character  (dch1)  capability  is not necessarily
+       employed.

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.
+       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".
