+.SH NAME
+\fBcurs_scroll\fR: \fBscroll\fR, \fBsrcl\fR, \fBwscrl\fR - scroll a
+\fBncurses\fR window
+.SH SYNOPSIS
+\fB#include <ncurses.h>\fR
+
+\fBint scroll(WINDOW *win);\fR
+.br
+\fBint scrl(int n);\fR
+.br
+\fBint wscrl(WINDOW *win, int n);\fR
+.br
+.SH DESCRIPTION
+The \fBscroll\fR 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.
+
+With the \fBscrl\fR and \fBwscrl\fR routines, for positive \fIn\fR scroll the
+window up \fIn\fR lines (line \fIi\fR+\fIn\fR becomes \fIi\fR); otherwise
+scroll the window down \fIn\fR lines.  This involves moving the lines in the
+window character image structure.  The current cursor position is not changed.
+
+For these functions to work, scrolling must be enabled via \fBscrollok\fR.
+.SH RETURN VALUE
+All routines return the integer \fBERR\fR upon failure and an integer value
+other than \fBERR\fR upon successful completion.
+.SH NOTES
+Note that \fBscrl\fR and \fBscroll\fR may be macros.
