Protocol - 3

Description

EfiPy2 also supports gBS.InstallMultipleProtocolInterfaces().
By EDK II definition,

typedef
EFI_STATUS
(EFIAPI *EFI_INSTALL_MULTIPLE_PROTOCOL_INTERFACES)(
  IN OUT EFI_HANDLE           *Handle,
  ...
  );

EfiPy2 follows this rule as possible as it can. 

EFI_INSTALL_MULTIPLE_PROTOCOL_INTERFACES = CFUNCTYPE (

  EFI_STATUS,

  POINTER(EFI_HANDLE)  # IN OUT *Handle

  )

In run time, EfiPy2 changes ctypes CFUNCTYPE argument by re-arrange arguments members.

EfiPy.gBS.InstallMultipleProtocolInterfaces.argtypes = [

      EfiPy.POINTER(EfiPy.EFI_HANDLE),

      EfiPy.POINTER(EfiPy.EFI_GUID),

      EfiPy.POINTER(EfiPy.PVOID),

      EfiPy.POINTER(EfiPy.PVOID)

      ]

Finally, calling EfiPy.gBS.InstallMultipleProtocolInterfaces() for install protocols in one time.

Status = EfiPy.gBS.InstallMultipleProtocolInterfaces (

               EfiPy.byref (Handle1),

               EfiPy.byref (TestGuid1),

               EfiPy.byref (TestProtocol1),

               None

               )

The same is as EfiPy.gBS.UninstallMultipleProtocolInterfaces()
