NAME

delch, wdelch, mvdelch, mvwdelch - delete character under the cursor in a curses window

CONTENTS

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.

Functions with a ``mv'' prefix first perform a cursor movement using wmove, and return an error if the position is outside the window, or if the window pointer is null.

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.

A typical Unix /bin or /usr/bin directory contains a hundred different kinds of programs, written by dozens of egotistical programmers, each with its own syntax, operating paradigm, rules of use ... strategies for specifying options, and different sets of constraints.
