August 18, 2014 simple question about function call syntax | ||||
---|---|---|---|---|
| ||||
I found this code sample in vibe: void connect(NetworkAddress addr) { enforce(.connect(m_ctx.socketfd, addr.sockAddr, addr.sockAddrLen) == 0, "Failed to connect UDP socket."~to!string(getLastSocketError())); } What does mean ".connect"? Where I can find description of this syntax (dot + function name)? |

. is the module-scope. Use it to dis-ambiguate between a module-global symbol and a function local symbol with same name.

Correct link: > > Module Scope Operator > http://dlang.org/module.html my link is correct too. ;-) quote: .Identifier Identifier is looked up at module scope, rather than the current lexically nested scope. but your is better. |
