.SH Description
.NXR "idlok subroutine"
If enabled 
.PN (bf
is 
.PN TRUE),
.PN curses
uses the insert/delete line hardware of terminals
if it is available.  
If disabled,
.PN curses
will not use this feature.  
This option should be enabled only if the
application needs insert/delete line; for example, for a screen
editor.  
It is disabled by default as insert/delete line
can be visually annoying when used in 
some applications.
.PP
If insert/delete line cannot be used,
.PN curses
will redraw the changed portions of all lines.
.NT
The terminal hardware insert/delete character feature
is always used if available.
.NE
.SH Return Values
The
.PN idlok
function returns OK on success and ERR on error.
