curs_delch(3x)                                           curs_delch(3x)




NAME

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


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 fea-
       ture.)


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  move-
       ment  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.
