scrl
curs_scroll(3) Library Functions Manual curs_scroll(3)NAME
curs_scroll, scroll, scrl, wscrl - Scroll a Curses window
SYNOPSIS
#include <curses.h>
int scroll(
WINDOW *win ); int scrl(
int n ); int wscrl(
WINDOW *win,
int n );
LIBRARY
Curses Library (libcurses)
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
scrl, wscrl, scroll: XCURSES4.2
Refer to the standards(5) reference page for more information about industry standards and associated tags.
DESCRIPTION
The scroll routine scrolls the window up one line. This involves moving the lines in the window data structure. As an optimization, if the
scrolling region of the window is the entire screen, the physical screen is scrolled at the same time.
The scrl and wscrl routines, for positive n, scroll the current or specified window up n lines (line i+n becomes line i); otherwise, these
routines scroll the window down n lines. This operation involves moving the lines in the window character-image structure. The routines do
not change the current cursor position.
For the scroll, scrl, and wscrl functions to work, the scrollok option must be enabled.
NOTES
The header file <curses.h> automatically includes the header file <stdio.h>.
Note that scrl may be a macro.
RETURN VALUES
All routines return the integer ERR upon failure and OK upon successful completion.
