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.
