delch(3XCURSES) X/Open Curses Library Functions delch(3XCURSES)
NAME
delch, mvdelch, mvwdelch, wdelch - remove a character
SYNOPSIS
cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib
-R /usr/xpg4/lib -lcurses [ library... ]
c89 [ flag... ] file... -lcurses [ library... ]
#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
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.
