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.
