Get the output style, canonical or not.
Set the output style to canonical, or not.
returns a string which shows ancillarydata in human-readable form.
p Socket::AncillaryData.new(:INET6, :IPV6, :PKTINFO, "").inspect #=> "#<Socket::AncillaryData: INET6 IPV6 PKTINFO \"\">"
returns the timestamp as a time object.
ancillarydata should be one of following type:
SOL_SOCKET/SCM_TIMESTAMP (microsecond) GNU/Linux, FreeBSD, NetBSD, OpenBSD, Solaris, MacOS X
SOL_SOCKET/SCM_TIMESTAMPNS (nanosecond) GNU/Linux
SOL_SOCKET/SCM_BINTIME (2**(-64) second) FreeBSD

Addrinfo.udp("127.0.0.1", 0).bind {|s2| s1.setsockopt(:SOCKET, :TIMESTAMP, true) s2.send "a", 0, s1.local_address ctl = s1.recvmsg.last p ctl #=> #<Socket::AncillaryData: INET SOCKET TIMESTAMP 2009-02-24 17:35:46.775581> t = ctl.timestamp p t #=> 2009-02-24 17:35:46 +0900 p t.usec #=> 775581 p t.nsec #=> 775581000 }
}
Returns a string to show contents of ifaddr.
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>"
Calls String#unpack on sockopt.data.
sockopt = Socket::Option.new(:INET, :SOCKET, :KEEPALIVE, [1].pack("i")) p sockopt.unpack("i") #=> [1] p sockopt.data.unpack("i") #=> [1]
Logs a message at the unknown (syslog alert) log level, or logs the message returned from the block.
Inputs string into the end of input buffer and skips data until a full flush point can be found. If the point is found in the buffer, this method flushes the buffer and returns false. Otherwise it returns true and the following data of full flush point is preserved in the buffer.
Returns last modification time recorded in the gzip file header.
Same as IO#sync
Same as IO. If flag is true, the associated IO object must respond to the flush method. While sync mode is true, the compression ratio decreases sharply.
Specify the modification time (mtime) in the gzip header. Using an Integer.
Setting the mtime in the gzip header does not effect the mtime of the file generated. Different utilities that expand the gzipped files may use the mtime header. For example the gunzip utility can use the ‘-N` flag which will set the resultant file’s mtime to the value in the header. By default many tools will set the mtime of the expanded file to the mtime of the gzipped file, not the mtime in the header.
If you do not set an mtime, the default value will be the time when compression started. Setting a value of 0 indicates no time stamp is available.
Returns the rest of the data which had read for parsing gzip format, or nil if the whole gzip file is not parsed yet.
Reads at most maxlen bytes from the gziped stream but it blocks only if gzipreader has no data immediately available. If the optional outbuf argument is present, it must reference a String, which will receive the data. It raises EOFError on end of file.

Returns the last access time for this file as an object of class Time.
File.stat("testfile").atime #=> Wed Dec 31 18:00:00 CST 1969
Returns the modification time of stat.
File.stat("testfile").mtime #=> Wed Apr 09 08:53:14 CDT 2003
Returns the birth time for stat.
If the platform doesn’t have birthtime, raises NotImplementedError.
File.write("testfile", "foo") sleep 10 File.write("testfile", "bar") sleep 10 File.chmod(0644, "testfile") sleep 10 File.read("testfile") File.stat("testfile").birthtime #=> 2014-02-24 11:19:17 +0900 File.stat("testfile").mtime #=> 2014-02-24 11:19:27 +0900 File.stat("testfile").ctime #=> 2014-02-24 11:19:37 +0900 File.stat("testfile").atime #=> 2014-02-24 11:19:47 +0900
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 the named file is a directory, or a symlink that points at a directory, and false otherwise.
file_name can be an IO object.
