curs_delch(3X) curs_delch(3X)
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.
