Try this program, it might answer your question.
I think you have to register two methods, one for the T type and one
for the F type, and check the types[] array in the handler.  I'm not
sure off-hand what role the argv[] array plays in this case, since it
seems to increment the index even though it doesn't carry useful
information.  I think it's just a placeholder to make for-loops over
argv easier.  (Steve H. will correct me if I'm wrong.. :)

int bool_handler(const char *path, const char *types,
                 lo_arg **argv, int argc,
                 void *data, void *user_data)
{
    printf("Message: %s, %s, %d\n",
           &argv[0]->s,
           types[1]==LO_TRUE ? "true" : types[1]==LO_FALSE ? "false" : "?",
           argv[2]->i);
}

int main()
{
    lo_server_thread s = lo_server_thread_new("8000", 0);
    lo_address a = lo_address_new("localhost", "8000");
    lo_server_thread_add_method(s, "/bool", "sTi", bool_handler, 0);
    lo_server_thread_add_method(s, "/bool", "sFi", bool_handler, 0);

Mistakes can happen. Keep it up :)

Okay, I've replaced the 0.25 release with one that actually works.
It should be spreading to the mirrors right now.
I also noticed I messed up tagging the release in svn, so I fixed that too.

Sorry for the newbie mistakes folks!

Looks like I messed up, sorry about that.
The "make dist" command didn't include that new header file and I
failed to notice.
I'll have to fix it.
In the meantime, please find that file here:

Hi!

I tried compiling the new version of liblo but compilation failed with the 
following error:

message.c:30:25: error: lo_internal.h: No such file or directory
message.c: In function ‘lo_get_path’:
message.c:436: warning: implicit declaration of function ‘lo_validate_string’
make[3]: *** [liblo_la-message.lo] Error 1
make[3]: Leaving directory `/usr/src/ljt_tmp/liblo-0.25/src'
make[2]: *** [all-recursive] Error 1

The file 'lo_internal.h' is indeed not present.

Any help appreciated.

Grs,
Heinz
