unixconn

UnixConn tools

Some stuff commonly used made more simple.

socketpair

Calling

	pair, err := unixconn.Pair()

Allows pair to contain two *net.UnixConn that are connected to each other. Those can be used as replacement to TCP connections in test code, for example.

cred

Golang already makes this easier thanks to GetsockoptUcred but I feel this can be even better.

	uid, gid, pid, err := unixconn.Cred(c)

NOTE: Using unixconn.Cred() on a connection generated by unixconn.Pair() will return the information at the time the call to Pair() happened, and may not reflect the right information if for example the socket was passed to a child process.
