CURSES_DELCH(3) 					   BSD Library Functions Manual 					   CURSES_DELCH(3)

NAME

     curses_delch, delch, wdelch -- curses delete characters routines

LIBRARY

     Curses Library (libcurses, -lcurses)

SYNOPSIS

     #include <curses.h>

     int
     delch(void);

     int
     wdelch(WINDOW *win);

DESCRIPTION

     These functions delete characters from stdscr or from the specified window.

     The delch() function deletes the character at the current cursor position on stdscr.  Characters to the right of the deleted character are
     moved one position to the left.  The cursor position is unchanged.

     The wdelch() function is the same as the delch() function, excepting that the character is deleted from the specified window.

RETURN VALUES

     Functions returning pointers will return NULL if an error is detected.  The functions that return an int will return one of the following
     values:

     OK   The function completed successfully.
     ERR  An error occurred in the function.

NAME

       delch, mvdelch, mvwdelch, wdelch - remove a character

SYNOPSIS

       cc [ flag... ] file... -I /usr/xpg4/include  -L	/usr/xpg4/lib 
	-R  /usr/xpg4/lib  -lcurses  [ library... ]

       c89 [ flag... ] file... -lcurses [ library... ]

       #include <curses.h>

       int delch(void);

       int mvdelch(int y, int x);

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

       int wdelch(WINDOW *win);

DESCRIPTION

       The  delch()  and wdelch() functions delete the character at  the current cursor position from stdscr and win, respectively.  All remaining
       characters after cursor through to the end of the line are shifted one character towards the start of the line. The last character  on  the
       line becomes a space; characters on other lines are  not affected.

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

PARAMETERS

       y      Is the y (row) coordinate of the position of the character  to be removed.

       x      Is the x (column) coordinate of the position of the character  to be removed.

       win    Is a pointer to the window containing the character to be removed.

RETURN VALUES

       On success, these functions return OK. Otherwise, they return ERR.

ERRORS

       None.
