= Win32 Registry
win32/registry is registry accessor library for Win32 platform.
It uses fiddle/import to call Win32 Registry APIs.
== example
Win32::Registry::HKEY_CURRENT_USER.open('SOFTWARE\foo') do |reg|
value = reg['foo'] # read a value
value = reg['foo', Win32::Registry::REG_SZ] # read a value with type
type, value = reg.read('foo') # read a value
reg['foo'] = 'bar' # write a value
reg['foo', Win32::Registry::REG_SZ] = 'bar' # write a value with type
reg.write('foo', Win32::Registry::REG_SZ, 'bar') # write a value
reg.each_value { |name, type, data| ... } # Enumerate values
reg.each_key { |key, wtime| ... } # Enumerate subkeys
reg.delete_value(name) # Delete a value
reg.delete_key(name) # Delete a subkey
reg.delete_key(name, true) # Delete a subkey recursively
