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.
