.Sh DESCRIPTION
|
||
|
|
These functions delete a single line from
|
||
|
|

|
||
|
|
or from the specified window.
|
||
|
|
.Pp
|
||
|
|

|
||
|
|
.Fn deleteln
|
||
|
|
function deletes the screen line containing the cursor in the
|
||
|
|
.Dv stdscr .
|
||
|
|
The
|
||
|
|
.Fn wdeleteln
|
||
|
|
function is the same as the
|
||
|
|
.Fn deleteln
|
||
|
|
function, excepting that the line is deleted from the window specified by
|
||
|
|
.Fa win .
|
||
|
|
.Pp
|
||
|
|
All lines following the deleted line are moved up one line toward the cursor.
|
||
|
|
The last line of the window is cleared.
|
||
|
|
The cursor position is unchanged.
|
||
|
|

or
|
||
|
|
.Fn wsetscrreg
|
||
|
|

|
||
|
|
then only the lines from the current line to the bottom of the scrolling

|
region are moved up and the bottom line of the scrolling region cleared.

||
|
|
.Pp
|
||
|
|

||
|
|
.Fn deleteln
|
||
|
|
and
|
||
|
|
.Fn wdeleteln win
|
||
|
|
are equivalent to

|
|
.Fn winsdelln stdscr \-1
|
||
|
|
and

|
|
.Fn winsdelln win \-1
