static VALUE
unix_recvfrom(int argc, VALUE *argv, VALUE sock)
{
return rsock_s_recvfrom(sock, argc, argv, RECV_UNIX);
}
Receives a message via unixsocket.
maxlen is the maximum number of bytes to receive.
flags should be a bitwise OR of Socket::MSG_* constants.
outbuf will contain only the received data after the method call even if it is not empty at the beginning.
Example
s1 = Socket.new(:UNIX, :DGRAM, 0) s1_ai = Addrinfo.unix("/tmp/sock1") s1.bind(s1_ai) s2 = Socket.new(:UNIX, :DGRAM, 0) s2_ai = Addrinfo.unix("/tmp/sock2") s2.bind(s2_ai) s3 = UNIXSocket.for_fd(s2.fileno) s1.send "a", 0, s2_ai p s3.recvfrom(10) #=> ["a", ["AF_UNIX", "/tmp/sock1"]]
