Returns the source encoding name as a string.
Returns the source encoding name as a string.
Parses a C struct’s members
Example:
require 'fiddle/import' include Fiddle::CParser #=> Object parse_struct_signature(['int i', 'char c']) #=> [[Fiddle::TYPE_INT, Fiddle::TYPE_CHAR], ["i", "c"]] parse_struct_signature(['char buffer[80]']) #=> [[[Fiddle::TYPE_CHAR, 80]], ["buffer"]]
Writes a number of random generated bytes (currently 1024) to filename which can be used to initialize the PRNG by calling ::load_random_file in a later session.
Retrieves the pre-configured API key key or terminates interaction with an error.
Add the –source option
Returns value specified by the member name of VT_RECORD OLE object. If the member name is not correct, KeyError exception is raised. If you can’t access member variable of VT_RECORD OLE object directly, use this method.
If COM server in VB.NET ComServer project is the following:
Imports System.Runtime.InteropServices Public Class ComClass Public Structure ComObject Public object_id As Ineger End Structure End Class
and Ruby Object class has title attribute:
then accessing object_id of ComObject from Ruby is as the following:
srver = WIN32OLE.new('ComServer.ComClass') obj = WIN32OLE_RECORD.new('ComObject', server) # obj.object_id returns Ruby Object#object_id obj.ole_instance_variable_get(:object_id) # => nil
Sets value specified by the member name of VT_RECORD OLE object. If the member name is not correct, KeyError exception is raised. If you can’t set value of member of VT_RECORD OLE object directly, use this method.
If COM server in VB.NET ComServer project is the following:
Imports System.Runtime.InteropServices
Public Class ComClass
<MarshalAs(UnmanagedType.BStr)> _
Public title As String
Public cost As Integer
End Class
then setting value of the ‘title’ member is as following:
srver = WIN32OLE.new('ComServer.ComClass') obj = WIN32OLE_RECORD.new('Book', server) obj.ole_instance_variable_set(:title, "The Ruby Book")
Re-composes a prime factorization and returns the product.
For the decomposition:
[[p_1, e_1], [p_2, e_2], ..., [p_n, e_n]],
it returns:
p_1**e_1 * p_2**e_2 * ... * p_n**e_n.
pd
Array of pairs of integers. Each pair consists of a prime number – a prime factor – and a natural number – its exponent (multiplicity).
Prime.int_from_prime_division([[3, 2], [5, 1]]) #=> 45 3**2 * 5 #=> 45
Constant time memory comparison for fixed length strings, such as results of HMAC calculations.
Returns true if the strings are identical, false if they are of the same length but not identical. If the length is different, ArgumentError is raised.
Returns the curve name (sn).
See the OpenSSL documentation for EC_GROUP_get_curve_name()
See the OpenSSL documentation for ECDSA_verify()
Returns true if key is the corresponding private key to the Subject Public Key Information, false otherwise.
Serializes the private key to DER-encoded PKCS #8 format. If called without arguments, unencrypted PKCS #8 PrivateKeyInfo format is used. If called with a cipher name and a password, PKCS #8 EncryptedPrivateKeyInfo format with PBES2 encryption scheme is used.
