CURSES_DELETELN(3)      NetBSD Library Functions Manual     CURSES_DELETELN(3)


NAME

     curses_deleteln, deleteln, wdeleteln -- curses delete single line rou-
     tines


LIBRARY

     Curses Library (libcurses, -lcurses)


SYNOPSIS

     #include <curses.h>

     int
     deleteln(void);

     int
     wdeleteln(WINDOW *win);


DESCRIPTION

     These functions delete a single line from stdscr or from the specified
     window.

     The deleteln() function deletes the screen line containing the cursor in
     the stdscr.  The wdeleteln() function is the same as the deleteln() func-
     tion, excepting that the line is deleted from the window specified by
     win.

     All lines following the deleted line are moved up one line toward the
     cursor.  The last line of the window is cleared.  The cursor position is
     unchanged.

     If a scrolling region has been set with the setscrreg() or wsetscrreg()
     functions and the current cursor position is inside the scrolling region,
     then only the lines from the current line to the bottom of the scrolling
     region are moved up and the bottom line of the scrolling region cleared.

     The functions deleteln() and wdeleteln(win) are equivalent to
     winsdelln(stdscr, -1) and winsdelln(win, -1) respectively.


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.
