How can I get an NSSocketPort to use a Unix-domain socket transport?
The docs for NSSocketPort don't specify TCP/IP, only a "BSD socket",
so it would seem that this should be possible. Only I haven't been
able to get it to work.
On the server side I'm trying to set up the NSSocketPort with
-initWithProtocolFamily:socketType:protocol:address. So, family
AF_UNIX, check, socketType SOCK_STREAM, check, protocol PF_UNIX,
check. But "address" is described in the docs as "...family-specific
socket address for the receiver copied into an NSData object". What's
that?
[...]
I also thought maybe I should set up a struct sockaddr_un, like I was
going to work directly with the socket, and then wrap up the struct in
an NSData:
struct sockaddr_un name;
memset(&name, 0, sizeof(struct sockaddr_un));
name.sun_family = AF_UNIX;
strcpy(name.sun_path, "/tmp/af_unix.test");
int len = sizeof(name.sun_family) + strlen(name.sun_path);
NSData *addrData = [NSData dataWithBytes:&name length:len];
But that didn't work any better.
Try changing that last line to:
NSData * addrData = [NSData dataWithBytes:&name length:sizeof
(name)];
