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  speci-
       fied).  (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 comple-
       tion.

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.
