Method: UNIXSocket.socketpair

Defined in:
unixsocket.c

.pair([type [, protocol]]) ⇒ Array .socketpair([type [, protocol]]) ⇒ Array

Creates a pair of sockets connected each other.

socktype should be a socket type such as: :STREAM, :DGRAM, :RAW, etc.

protocol should be a protocol defined in the domain. 0 is default protocol for the domain.

s1, s2 = UNIXSocket.pair
s1.send "a", 0
s1.send "b", 0
p s2.recv(10) #=> "ab"

Overloads:

  • .pair([type [, protocol]]) ⇒ Array

    Returns:

    • (Array)
  • .socketpair([type [, protocol]]) ⇒ Array

    Returns:

    • (Array)
