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.
