+.SH NAME
+\fBdeleteln\fR,
+\fBwdeleteln\fR,
+\fBinsdelln\fR,
+\fBwinsdelln\fR,
+\fBinsertln\fR,
+\fBwinsertln\fR - delete and insert lines in a \fBcurses\fR window
+.SH SYNOPSIS
+\fB#include <curses.h>\fR
+.sp
+\fBint deleteln(void);\fR
+.br
+\fBint wdeleteln(WINDOW *win);\fR
+.br
+\fBint insdelln(int n);\fR
+.br
+\fBint winsdelln(WINDOW *win, int n);\fR
+.br
+\fBint insertln(void);\fR
+.br
+\fBint winsertln(WINDOW *win);\fR
+.br
+.SH DESCRIPTION
+The \fBdeleteln\fR and \fBwdeleteln\fR routines delete the line under the
+cursor in the window; all lines below the current line are moved up one line.
+The bottom line of the window is cleared. The cursor position does not change.
+.PP
+The \fBinsdelln\fR and \fBwinsdelln\fR routines, for positive \fIn\fR, insert
+\fIn\fR lines into the specified window above the current line. The \fIn\fR
+bottom lines are lost. For negative \fIn\fR, delete \fIn\fR lines (starting
+with the one under the cursor), and move the remaining lines up. The bottom
+\fIn\fR lines are cleared. The current cursor position remains the same.
+.PP
+The \fBinsertln\fR and \fBwinsertln\fR routines insert a blank line above the
+current line and the bottom line is lost.
+.SH RETURN VALUE
+All routines return the integer \fBERR\fR upon failure and an \fBOK\fR (SVr4
+specifies only "an integer value other than \fBERR\fR") upon successful
+completion.
+.PP
+X/Open defines no error conditions.
+In this implementation,
+if the window parameter is null, an error is returned.
+.SH PORTABILITY
+These functions are described in the XSI Curses standard, Issue 4. The
+standard specifies that they return \fBERR\fR on failure, but specifies no
+error conditions.
+.SH NOTES
+Note that all but \fBwinsdelln\fR may be macros.
+.PP
+These routines do not require a hardware line delete or insert feature in the
+terminal. In fact, they will not use hardware line delete/insert unless
+\fBidlok(..., TRUE)\fR has been set on the current window.
