Partial Load ARX file?

Is it possible to do a partial load of an ARX file? I've got McNeel's DOSLIB, but the only function I need is the "dos_beep" function...I don't want everything else sitting in memory all the time for the occasional use of one function.

Any ideas?

Thanks.

(vl-cmdf "vbastmt" "beep")

or


(vlr-beep-reaction)

For what it's worth, here's I handle DosLib...

(defun LoadDosLib ()
(if (null dos_about)(arxload (strcat LSPDir "doslib2004")))
)

(defun UnloadDosLib ()
(if (not (null dos_about)) (command "arx" "unload" "doslib2004"))
)

(defun C:Test ( / )
(LoadDosLib) ; Load DosLib
(dos_beep) ; Perform some action/command
(UnLoadDosLib) ; Unload DosLib
(princ)
)

 

Thanks for the response. That's good enough for what I need it for.

I'm surprised you'd take that route, as compared to Bill's earlier
suggestion of (vlr-beep-reaction), which is a built-in function that doesn't
require a 3rd party application or any loading or unloading. I use doslib
for other things, but wouldn't fool with it just for a beep.

Per the original question, I'm not aware of any harm being done by doslib
being present in memory. But I have a pretty good idea that Acad doesn't
surrender all its RAM when it closes a drawing. This is based on the fact
that that when I run scripts in SDI (using a bare-bones profile with nothing
being loaded, no doslib, not even a menu) I will inevitable have an out of
memory error after 200 or 300 drawings, and need to reboot to continue.
That's with small drawings, generally under 500K.

From this experience, I wonder if memory is always fully released when an
arx is unloaded. If anything, I'd be more suspicious of creeping memory loss
from continually loading and unloading a 300K file utility every time you
want a beep, versus just loading the beeper once and leaving it alone.
