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.
Find
(and return) first subnode (recursively) for which the block evaluates to true. Returns nil
if none was found.
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.
pd
Array
of pairs of integers. The each internal pair consists of a prime number – a prime factor – and a natural number – an exponent.
For [[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. Prime.int_from_prime_division([[2,2], [3,1]]) #=> 12
Returns the curve name (sn).

documentation for EC_GROUP_get_curve_name()
Returns true
if key is the corresponding private key to the Subject Public Key Information, false
otherwise.
