curs_delch, delch, wdelch, mvdelch, mvwdelch - delete character under cursor in a curses window
cc [ flag ... ] file ... –lcurses [ library ... ] #include <curses.h> int delch(void);
int wdelch(WINDOW *win);
int mvdelch(int y, int x);
int mvwdelch(WINDOW *win, int y, int x);
With these routines the character under the cursor in the window is deleted; 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.
All routines return the integer ERR upon failure and an integer value other than ERR upon successful completion.

The header <curses.h> automatically includes the headers <stdio.h> and <unctrl.h>.
Note that delch(), mvdelch(), and mvwdelch() may be macros.
