delch(), mvdelch(), mvwdelch(), wdelch()

delete character under the cursor in a curses window 

Curses Function


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 VALUES

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.
