+.SH NAME
+\fBcurs_deleteln\fR: \fBdeleteln\fR, \fBwdeleteln\fR, \fBinsdelln\fR,
+\fBwinsdelln\fR, \fBinsertln\fR, \fBwinsertln\fR - delete and insert
+lines in a \fBncurses\fR window
+.SH SYNOPSIS
+\fB#include <ncurses.h>\fR
+
+\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.
+
+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.
+
+The \fBinsertln\fR and \fBinsertln\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 integer
+value other than \fBERR\fR upon successful completion.
+.SH BUGS
+All the above should be implemented through \fBwinsdelln\fR() but
+currently only \fBinsdelln\fR() is implemented in terms of it.
+.SH NOTES
+Note that all but \fBwinsdelln\fR may be a macros.
+
+These routines do not require a hardware line delete or insert feature in the
+terminal.  In fact, they won't use hardware line delete/insert unless
+\fBidlok(..., TRUE)\fR has been set on the current window.
