D bindings for Bonjour

[Vincent R via Digitalmars-d-learn]

Hi,

I am starting my first project in D and I would like to do a 
Bonjour(Zeroconf) browser app.
My first task is to write a binding to the dns_sd library but I 
have an issue with the following macro:

#define kDNSServiceOutputFlags (kDNSServiceFlagsValidate | 
kDNSServiceFlagsValidateOptional | kDNSServiceFlagsMoreComing | 
kDNSServiceFlagsAdd | kDNSServiceFlagsDefault)

It justs takes some enum (defined above but not shown here) and 
do a OR operation on it.

How can I express that in D ?

Do I need to use a template  as shown here 
http://wiki.dlang.org/D_binding_for_C or a varg function ?

Thanks
