| 53 | .SH DESCRIPTION
|
|---|
| 54 | The \fBdeleteln\fR and \fBwdeleteln\fR routines delete the line under the
|
|---|
| 55 | cursor in the window; all lines below the current line are moved up one line.
|
|---|
| 56 | The bottom line of the window is cleared. The cursor position does not change.
|
|---|
| 57 |
|
|---|
| 58 | The \fBinsdelln\fR and \fBwinsdelln\fR routines, for positive \fIn\fR, insert
|
|---|
| 59 | \fIn\fR lines into the specified window above the current line. The \fIn\fR
|
|---|
| 60 | bottom lines are lost. For negative \fIn\fR, delete \fIn\fR lines (starting
|
|---|
| 61 | with the one under the cursor), and move the remaining lines up. The bottom
|
|---|
| 62 | \fIn\fR lines are cleared. The current cursor position remains the same.
|
|---|
| 63 |
|
|---|
| 64 | The \fBinsertln\fR and \fBwinsertln\fR routines insert a blank line above the
|
|---|
| 65 | current line and the bottom line is lost.
|
|---|
| 66 | .SH RETURN VALUE
|
|---|
| 67 | All routines return the integer \fBERR\fR upon failure and an \fBOK\fR (SVr4
|
|---|
| 68 | specifies only "an integer value other than \fBERR\fR") upon successful
|
|---|
| 69 | completion.
|
|---|
| 70 | .PP
|
|---|
| 71 | X/Open defines no error conditions.
|
|---|
| 72 | In this implementation,
|
|---|
| 73 | if the window parameter is null, an error is returned.
|
|---|
| 74 | .SH PORTABILITY
|
|---|
| 75 | These functions are described in the XSI Curses standard, Issue 4. The
|
|---|
| 76 | standard specifies that they return \fBERR\fR on failure, but specifies no
|
|---|
| 77 | error conditions.
|
|---|
| 78 | .SH NOTES
|
|---|
| 79 | Note that all but \fBwinsdelln\fR may be macros.
|
|---|
| 80 |
|
|---|
| 81 | These routines do not require a hardware line delete or insert feature in the
|
|---|
| 82 | terminal. In fact, they won't use hardware line delete/insert unless
|
|---|
| 83 | \fBidlok(..., TRUE)\fR has been set on the current window.
