Creates a new Socket::Option object for SOL_SOCKET/SO_LINGER.
onoff should be an integer or a boolean.
secs should be the number of seconds.
p Socket::Option.linger(true, 10) #=> #<Socket::Option: UNSPEC SOCKET LINGER on 10sec>
Returns the linger data in sockopt as a pair of boolean and integer.
sockopt = Socket::Option.linger(true, 10) p sockopt.linger => [true, 10]
Same as IO.

Symmetric Householder reduction to tridiagonal form.
Returns true if U, and hence A, is singular.
Puts the connection into binary (image) mode, issues the given command, and fetches the data returned, passing it to the associated block in chunks of blocksize characters. Note that cmd is a server command (such as “RETR myfile”).
Puts the connection into ASCII (text) mode, issues the given command, and passes the resulting data, one line at a time, to the associated block. If no block is given, prints the lines. Note that cmd is a server command (such as “RETR myfile”).
Puts the connection into binary (image) mode, issues the given server-side command (such as “STOR myfile”), and sends the contents of the file named file to the server. If the optional block is given, it also passes it the data, in chunks of blocksize characters.
