Allocates a C struct with the types provided.
When the instance is garbage collected, the C function func is called.
Allocates a C union the types provided.
When the instance is garbage collected, the C function func is called.
Fiddle::Pointer.malloc(size, freefunc = nil) => fiddle pointer instance
Allocate size bytes of memory and associate it with an optional freefunc that will be called when the pointer is garbage collected.
freefunc must be an address pointing to a function or an instance of Fiddle::Function
Returns a string formatted with an easily readable representation of the internal state of the pointer.
Returns the remaining data held in the cipher object. Further calls to Cipher#update or Cipher#final will return garbage. This call should always be made as the last call of an encryption or decryption operation, after having fed the entire plaintext or ciphertext to the Cipher instance.
If an authenticated cipher was used, a CipherError is raised if the tag could not be authenticated successfully. Only call this method after setting the authentication tag and passing the entire contents of the ciphertext into the cipher.
Enables or disables padding. By default encryption operations are padded using standard block padding and the padding is checked and removed when decrypting. If the pad parameter is zero then no padding is performed, the total amount of data encrypted or decrypted must then be a multiple of the block size or an error will occur.
See EVP_CIPHER_CTX_set_padding for further information.
String representation of this configuration object, including the class name and its sections.
Returns an array of currently loaded engines.
Releases all internal structural references for this engine.
May raise an EngineError if the engine is unavailable
Pretty print this engine
Returns the authentication code as a hex-encoded string. The digest parameter must be an instance of OpenSSL::Digest.
key = 'key' data = 'The quick brown fox jumps over the lazy dog' digest = OpenSSL::Digest.new('sha1') hmac = OpenSSL::HMAC.hexdigest(digest, key, data) #=> "de7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9"
Emit a map. The coder will be yielded to the block.
Emit a map with value
The line number of the current token. This value starts from 1. This method is valid only in event handlers.
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 socket family as an integer.
p Socket::AncillaryData.new(:INET6, :IPV6, :PKTINFO, "").family #=> 10
Creates a new Socket::AncillaryData object which contains a int as data.
The size and endian is dependent on the host.
require 'socket' p Socket::AncillaryData.int(:UNIX, :SOCKET, :RIGHTS, STDERR.fileno) #=> #<Socket::AncillaryData: UNIX SOCKET RIGHTS 2>
Returns the data in ancillarydata as an int.
The size and endian is dependent on the host.
ancdata = Socket::AncillaryData.int(:UNIX, :SOCKET, :RIGHTS, STDERR.fileno) p ancdata.int #=> 2
Returns a string to show contents of ifaddr.
Returns the interface index of ifaddr.
