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.
File.directory?(".")
Returns true if new
is newer than all old_list
. Non-existent files are older than any file.
FileUtils.uptodate?('hello.o', %w(hello.c hello.h)) or \ system 'make hello.o'

FileUtils.uptodate?('hello.o', %w(hello.c hello.h)) or \ system 'make hello.o'
Updates modification time (mtime) and access time (atime) of file(s) in list
. Files are created if they don’t exist.
FileUtils.touch 'timestamp' FileUtils.touch Dir.glob('*.c'); system 'make'

Returns the result of converting the serialized data in source into a Ruby object (possibly with associated subordinate objects). source may be either an instance of IO
or an object that responds to to_str. If proc is specified, each object will be passed to the proc, as the object is being deserialized.
Never pass untrusted data (including user supplied input) to this method. Please see the overview for further details.
Initiates the SSL/TLS handshake as a client in non-blocking manner.
# 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.
Initiates the SSL/TLS handshake as a server in non-blocking manner.
# emulates blocking accept begin ssl.accept_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 accept_nonblock
should not raise an IO::WaitReadable
or IO::WaitWritable
exception, but return the symbol :wait_readable
or :wait_writable
instead.
A non-blocking version of sysread
. Raises an SSLError
if reading would block. If “exception: false” is passed, this method returns a symbol of :wait_readable, :wait_writable, or nil, rather than raising an exception.
Reads length bytes from the SSL
connection. If a pre-allocated buffer is provided the data will be written into it.
Writes string to the SSL
connection in a non-blocking manner. Raises an SSLError
if writing would block.
Returns the error string corresponding to the error code retrieved by error
.

Returns whether this EC
instance has a private key. The private key (BN
) can be retrieved with EC#private_key
.
Encrypt string with the private key. padding defaults to PKCS1_PADDING. The encrypted string output can be decrypted using public_decrypt
.
Decrypt string, which has been encrypted with the public key, with the private key. padding defaults to PKCS1_PADDING.
