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]
The line number of the last row read from this file.
Specify line number of the last row read from this file.

Returns the number of hard links to stat.
File.stat("testfile").nlink #=> 1 File.link("testfile", "testfile.bak") #=> 0 File.stat("testfile").nlink #=> 2
Returns true if stat is a symbolic link, false if it isn’t or if the operating system doesn’t support this feature. As File::stat automatically follows symbolic links, symlink? will always be false for an object returned by File::stat.
File.symlink("testfile", "alink") #=> 0 File.stat("alink").symlink? #=> false File.lstat("alink").symlink? #=> true
Returns true if stat has its sticky bit set, false if it doesn’t or if the operating system doesn’t support this feature.
File.stat("testfile").sticky? #=> false
Returns whether the buffer buffer is accessible.
A buffer becomes invalid if it is a slice of another buffer (or string) which has been freed or re-allocated at a different address.
Sends a TRACE request to the server; returns an instance of a subclass of Net::HTTPResponse.
The request is based on the Net::HTTP::Trace object created from string path and initial headers hash initheader.
http = Net::HTTP.new(hostname) http.trace('/todos/1')

Returns the value of the node as an IntegerNode or a FloatNode. This method is deprecated in favor of value or numerator/#denominator.
Returns the lines of the source code as an array of strings.
Binary search through the offsets to find the line number for the given byte offset.
Returns true if this comment happens on the same line as other code and false if the comment is by itself.
This can only be true for inline comments.
Returns true if there were no errors during parsing and false if there were.
Look up the typeclass DNS resource of name.
name must be a Resolv::DNS::Name or a String.
typeclass should be one of the following:
Resolv::DNS::Resource::IN::ANY
Resolv::DNS::Resource::IN::CNAME
Resolv::DNS::Resource::IN::HINFO
Resolv::DNS::Resource::IN::MINFO
Resolv::DNS::Resource::IN::MX
Resolv::DNS::Resource::IN::NS
Resolv::DNS::Resource::IN::PTR
Resolv::DNS::Resource::IN::SOA
Resolv::DNS::Resource::IN::TXT
Returned resource is represented as a Resolv::DNS::Resource instance, i.e. Resolv::DNS::Resource::IN::A.
Looks up all typeclass DNS resources for name. See getresource for argument details.
Return the authoritative instance of the command manager.
Returns self. Allows a CommandManager instance to stand in for the class itself.
True if the backtrace option has been specified, or debug is on.
True if the dependency will not always match the latest version.
