You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: sid.rb
    path of file: ./repos/puppet/lib/puppet/util/windows
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require_relative '../../../puppet/util/windows'

module Puppet::Util::Windows
  module SID
    require 'f
    
    def name_to_principal(name, allow_unresolved = false)
      # Apparently, we accept a symbol..
      name = name.to_s.strip if name

      # if name is a SID string, convert it to raw bytes for use with lookup_account_sid
      raw_sid_bytes = nil
      begin
        string_to_sid_ptr(name) do |sid_ptr|
          raw_sid_bytes = sid_ptr.read_array_of_uchar(get_length_sid(sid_ptr))
        end
      rescue => e
        # Avoid debug logs pollution with valid account names
        # https://docs.microsoft.com/en-us/windows/win32/api/sddl/nf-sddl-convertstringsidtosidw#return-value
        Puppet.debug("Could not retrieve raw SID bytes from '#{name}': #{e.message}") unless e.code == ERROR_INVALID_SID_STRUCTURE
      end
