- delete character under the cursor in a curses
int wdelch(WINDOW *win);
int mvdelch(int y, int x);
int mvwdelch(WINDOW *win, int y, int x);
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
, if specified).
(This does not
imply use of the hardware delete character feature.)
All routines return the integer ERR
upon failure and an OK
specifies only "an integer value other than ERR
") upon successful
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.
Note that delch
, and mvwdelch
may be macros.
These functions are described in the XSI Curses standard, Issue 4.
standard specifies that they return ERR
on failure, but specifies no
