Hi Mark,

I'm afraid the low level BSD socket structures are not yet covered by BridgeSupport.

We could eventually add them to the libSystem BridgeSupport file, however I wonder if there isn't an easier way to use Bonjour from MacRuby.

Hi,

For a distributed web service I am trying to add Bonjour support, but I ran into trouble with the Bridge Support when trying out one of the examples from the NSNetServices Programming Guide[1].

When publishing, I am supposed to get some socket info from a BSD sockaddr structure[2], but I can't seem to cast the Pointer object to something useful. For example, when I try asking the Pointer for its type I get this:

NSSocketPort.alloc.init.address.bytes.type # => "C"

But it should be a struct with a short int and a char array. If I try to case the Pointer I get an error:

NSSocketPort.alloc.init.address.bytes.cast!( '{sockaddr=s[c]}' )

TypeError: unrecognized runtime type `{sockaddr=s[c]}'

I cannot find a Boxed class descendant for sockaddr or any of the structs it is unionized with, so I am wondering if anybody else has tried the Bonjour examples with MacRuby and had success? Are these low-level BSD libraries supported by the new Bridge Support?

Thanks,
Mark
