Class Method Detail
Instance Method Detail
Accepts an incoming connection.
If the server is closed after invoking this method,
IO::Error
(closed stream) is raised.
require "socket"
server = TCPServer.new(2202)
socket = server.accept
socket.puts Time.now
socket.close
Accepts an incoming connection, yields it to the given block, and then closes the conneciton. Returns the value of the block.
If the server is closed after invoking this method,
IO::Error
(closed stream) is raised.
require "socket"
server = TCPServer.new(2202)
server.accept do |socket|
socket.puts Time.now
end
Accepts an incoming connection.
If the server is closed after invoking this method,
nil
is returned.
require "socket"
server = TCPServer.new(2202)
socket = server.accept?
if socket
socket.puts Time.now
socket.close
else
# This might happen if another fiber closes the server
# (can't happen in this example)
puts "server was closed"
end
Accepts an incoming connection, yields it to the given
block, and then closes the conneciton. Returns the
value of the block, or nil
if the server is closed
after invoking this method.
require "socket"
server = TCPServer.new(2202)
server.accept? do |socket|
