instance method

OpenSSL::SSL::SSLSocket#connect_nonblock

ssl.connect_nonblock([options]) => self

static VALUE
ossl_ssl_connect_nonblock(int argc, VALUE *argv, VALUE self)
{
    VALUE opts;
    rb_scan_args(argc, argv, "0:", &opts);

    ossl_ssl_setup(self);

    return ossl_start_ssl(self, SSL_connect, "SSL_connect", opts);
}

Initiates the SSL/TLS handshake as a client in non-blocking manner.

Example

# emulates blocking connect
begin
  ssl.connect_nonblock
rescue IO::WaitReadable
  IO.select([s2])
  retry
rescue IO::WaitWritable
  IO.select(nil, [s2])
  retry
end

By specifying a keyword argument exception to false, you can indicate that connect_nonblock should not raise an IO::WaitReadable or IO::WaitWritable exception, but return the symbol :wait_readable or :wait_writable instead.
