yes, that worked.

well spotted, that makes things a lot simpler and effectively fixes the 
problem twice

Hello once more,

I'm not sure how many people on this list care about Windows
compatibility, but I'll report this anyway:

The way how ...-style varargs are passed on within lo_cpp.h (lines 102,
115, ...) does not work under Windows (VS 2013).

I used to ignore the "'va_start' has undefined behavior with reference
types"-warning while compiling on OSX because everything worked fine.
But under Windows, using a reference type like &type as argument for
va_start messes up everything. (It works fine when I pass it by value...)

Regards,
Martin

This is not calling the function lo_address_free(), but only declaring it.  Try:

lo_address_free(t);

However, you don't need to do the lo_address_new() and
lo_address_free() inside the loop.  You can create the lo_address once
and use it to send all your messages.

i'm pretty new to working with c, so please excuse what may seem like 
simple questions. i've been writing a kinect - OSC application, or 
rather modifying an existing piece of code written by joaquim rocha [1]. 
i am using liblo to send the messages from my application to puredata, 
but get problems after 1021 have been sent. i messaged with stephen 
sinclair at the liblo project, and he said i was having problems from 
not using lo_address_free to clean up after sending a message, and i was 
likely running out of sockets. so, i added a line to free an address 
after each message was sent, recompiled and ran again. the lines below 
are the trivial piece of code i'm using to figure out how to use liblo 
before i work on the actual project. could someone advise what the 
problem is here? my code is still only sending 1021 messages, and 
netstat tells me i have many, many sockets open on my computer (about 
1030).

#include <lo/lo.h>
#include <lo/lo_lowlevel.h>

static int count;

main()
{
count=1;
while(1)
{
	lo_address t = lo_address_new("localhost", "9998");
	lo_send(t, "/sk", "ii", 1, count);
	count++;
	void lo_address_free(lo_address t);
	sleep(1);
}
}

What the world needs now, is love sweet love

Hello there,

after I finally got my (liblo-including) project ported to Windows, I'd
like to propose the following:


Please change line 25 in lo_osc_types.h from:

#ifdef _MSC_VER

...to something like:

#if defined(_MSC_VER) && _MSC_VER < 1600


Reason: since Version 2010 (= 1600), Visual Studio now comes with a
stdint.h. If that is included somewhere else in a project, the
re-definition causes ugly compiler errors ( error C2632).

Thanks,
Martin
