   mvdelch.3x    ( 3 )

Имя (Name)

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

---

Синопсис (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);

---

Описание (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.)

---

Возвращаемое значение (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.

---

Примечание (Note)

Note that delch, mvdelch, and mvwdelch may be macros.

---

Портативность (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.
