Module Name:

  EfiApi.h

Abstract:

  EFI intrinsic definitions. This includes all EFI 1.0 boot and runtime
  services APIs.

  Drivers and applications are passed in a pointer to the EFI system table.
  The EFI system table contains pointers to the boot and runtime services
  tables.

// BY_HANDLE_PROTOCOL    - Used by EFI 1.0 Drivers and Applications
//                         May not actually add an elemnt to the open list in a production build
//
// GET_PROTOCOL          - Used by EFI 1.1 Drivers to get a protocol interface
//                         May not actually add an elemnt to the open list in a production build
//
// TEST_PROTOCOL         - Used by EFI 1.1 Drivers to test for the existence of a protocol interface
//                         The interface is not returned, and it is an optional parameter tham may be NULL.
//                         May not actually add an elemnt to the open list in a production build
//
// BY_DRIVER             - Used by EFI 1.1 Drivers that are able to share a protocol with other
//                         agents other than its children.  A driver is always able to share
//                         a protocol with its children, since the driver is in control of the
//                         parent controller's and the child controller's use of the protocol.
//
// BY_DRIVER | EXCLUSIVE - Used by EFI 1.1 Drivers that will not share a protocol with any other
//                         agents except its children.  A driver is always able to share
//                         a protocol with its children, since the driver is in control of the
//                         parent controller's and the child controller's use of the protocol.
//                         This attribute will force all other drivers to disconnect from the protocol
//                         before this driver attaches.  When this driver closes the handle, the other
//                         drivers will reconnect to the protocol.
//
//
// BY_CHILD_CONTROLLER   - Used by EFI 1.1 Driver to show that a protocol is consumed by a child
//                         of the driver.  This is information used by DisconnectController() to
//                         determine the list of children that a protocol has.  It has
//                         no affect on the OpenProtocol()/ClosePrototocol() behavior.
//
// EXCLUSIVE             - Used by EFI 1.1 Applications to gain exclusive access to a protocol.
//                         All drivers are disconnected from the handle while the application has
//                         the handle open.  These drivers are reconnected when the application
//                         closes the handle.
