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 characters 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.
