delch wdelch mvdelch mvwdelch

The delch set of routines is used to remove a character.

Syntax

   #include <curses.h>



   int delch();

   int wdelch(WINDOW *win);



   int mvdelch(int y, int x);

   int mvwdelch(WINDOW *win, int y, int x);

Parameters

x: The x (column) coordinate of the position of the character to be removed.
y: The y (row) coordinate of the position of the character to be removed.
win: A pointer to the window containing the character to be removed.

Return Values

OK: Successful completion.
ERR: An error occurred.

Description

The delch() and wdelch() routines delete the character at the current cursor position from stdscr and win, respectively. All remaining characters on the same line to the right of the deleted character are moved left one character. The last character on the line becomes a space; characters on other lines are not affected.

The mvdelch() and mvwdelch() routines delete the character at the position specified by the x and y parameters; the former deletes the character from stdscr; the latter from win.




	NOTE: The `delch()`, `mvdelch()`, and `mvwdelch()` routines are macros.

Implementation Considerations

Identical to XPG/3

Portability

HP-UX, UNIX System V, XPG/3
