Returns the netmask address of ifaddr. nil is returned if netmask is not available in ifaddr.
returns the socket family as an integer.
p Socket::Option.new(:INET6, :IPV6, :RECVPKTINFO, [1].pack("i!")).family #=> 10
Returns a string which shows sockopt in human-readable form.
p Socket::Option.new(:INET, :SOCKET, :KEEPALIVE, [1].pack("i")).inspect #=> "#<Socket::Option: INET SOCKET KEEPALIVE 1>"
Creates a new Socket::Option object which contains an int as data.
The size and endian is dependent on the platform.
p Socket::Option.int(:INET, :SOCKET, :KEEPALIVE, 1) #=> #<Socket::Option: INET SOCKET KEEPALIVE 1>
Returns the data in sockopt as an int.
The size and endian is dependent on the platform.
sockopt = Socket::Option.int(:INET, :SOCKET, :KEEPALIVE, 1) p sockopt.int => 1
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]
Logs a message at the info (syslog info) log level, or logs the message returned from the block.
Returns true if the stream is finished.
Finishes the stream and flushes output buffer. If a block is given each chunk is yielded to the block until the input buffer has been flushed to the output buffer.
Decompresses string. Raises a Zlib::NeedDict exception if a preset dictionary is needed for decompression.
This method is almost equivalent to the following code:
def inflate(string) zstream = Zlib::Inflate.new buf = zstream.inflate(string) zstream.finish zstream.close buf end
See also Zlib.deflate
Inputs deflate_string into the inflate stream and returns the output from the stream. Calling this method, both the input and the output buffer of the stream are flushed. If string is nil, this method finishes the stream, just like Zlib::ZStream#finish.
If a block is given consecutive inflated chunks from the deflate_string are yielded to the block and nil is returned.
Raises a Zlib::NeedDict exception if a preset dictionary is needed to decompress. Set the dictionary by Zlib::Inflate#set_dictionary and then call this method again with an empty string to flush the stream:
inflater = Zlib::Inflate.new begin out = inflater.inflate compressed rescue Zlib::NeedDict # ensure the dictionary matches the stream's required dictionary raise unless inflater.adler == Zlib.adler32(dictionary) inflater.set_dictionary dictionary inflater.inflate '' end # ... inflater.close
See also Zlib::Inflate.new
Closes the GzipFile object. Unlike Zlib::GzipFile#close, this method never calls the close method of the associated IO object. Returns the associated IO object.
Same as IO.
Same as IO.
The line number of the last row read from this file.
Specify line number of the last row read from this file.
Resets the position of the file pointer to the point created the GzipReader object. The associated IO object needs to respond to the seek method.
See Zlib::GzipReader documentation for a description.
This is a deprecated alias for each_line.

Returns the number of hard links to stat.
File.stat("testfile").nlink #=> 1 File.link("testfile", "testfile.bak") #=> 0 File.stat("testfile").nlink #=> 2
Produce a nicely formatted description of stat.
File.stat("/etc/passwd").inspect #=> "#<File::Stat dev=0xe000005, ino=1078078, mode=0100644, # nlink=1, uid=0, gid=0, rdev=0x0, size=1374, blksize=4096, # blocks=8, atime=Wed Dec 10 10:16:12 CST 2003, # mtime=Fri Sep 12 15:41:41 CDT 2003, # ctime=Mon Oct 27 11:20:27 CST 2003, # birthtime=Mon Aug 04 08:13:49 CDT 2003>"
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
