curs_delch(3) UNIX Programmer's Manual curs_delch(3)NAME
delch, wdelch, mvdelch, mvwdelch - delete character under
the cursor in a curses window
SYNOPSIS
#include <curses.h>
int delch(void);
int wdelch(WINDOW *win);
int mvdelch(int y, int x);
int mvwdelch(WINDOW *win, int y, int x);
DESCRIPTION
These routines delete the character under the cursor; 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.)
RETURN VALUE
All routines return the integer ERR upon failure and an OK
(SVr4 specifies only "an integer value other than ERR") upon
successful completion.
NOTES
Note that delch, mvdelch, and mvwdelch may be macros.
PORTABILITY
These functions are described in the XSI Curses standard,
Issue 4. The standard specifies that they return ERR on
failure, but specifies no error conditions.
