#include <curses.h>
int delch(void);
int mvdelch(int y, int x);
int mvwdelch(WINDOW *win, int y, int x);
int wdelch(WINDOW *win);
DESCRIPTION
The delch() and wdelch() functions delete the character at the current
cursor position from stdscr and win, respectively. All remaining char‐
acters after cursor through to the end of the line are shifted one
character towards the start of the line. The last character on the line
becomes a space; characters on other lines are not affected.
The mvdelch() and mvwdelch() functions delete the character at the
position specified by the x and y parameters; the former deletes the
character from stdscr; the latter from win.
PARAMETERS
y Is the y (row) coordinate of the position of the character to
be removed.
x Is the x (column) coordinate of the position of the character
to be removed.
win Is a pointer to the window containing the character to be
removed.
RETURN VALUES
On success, these functions return OK. Otherwise, they return ERR.
ERRORS
None.
