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.
