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

enum kDNSServiceOutputFlags = (kDNSServiceFlagsValidate | kDNSServiceFlagsValidateOptional | kDNSServiceFlagsMoreComing | kDNSServiceFlagsAdd | kDNSServiceFlagsDefault);

Good luck :)

I wanted to delete my post when I realize the stupidity of my question. Actually I ask my question before really looking at it.
Sorry

Is there any central place where you store bindings ?

code.dlang.org -- general place for every d project

Ok thanks.
Sorry to ask so much question but how do you declare different calling conventions like the following macro:


#if defined(_WIN32)
#define DNSSD_API __stdcall
#else
#define DNSSD_API
#endif


From what I understand I could write:

version (Windows)
{
	extern (Windows)
	{
		int DNSServiceGetProperty
		(
		 in char *property,
		 void       *result,
		 uint       *size
		 );
	}
}
else
{
	extern (C)
	{
		int DNSServiceGetProperty
			(
			 in char *property,
			 void       *result,
			 uint       *size
				 );
	}
}

but I don't want to write it once.
How can I solve this ?
And if there is an easy fix what about writing it inside the wiki page:
http://wiki.dlang.org/D_binding_for_C

Thanks

This specific case is common enough to be built into the language: use `extern(System)` instead of Windows or C and the one declaration will work on both.

You can edit a wiki yourself!
