.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.
