Tests to see if this driver supports a given controller. If a child device is provided,

This function checks to see if the driver specified by This supports the device specified by
ControllerHandle. Drivers will typically use the device path attached to
ControllerHandle and/or the services from the bus I/O abstraction attached to
ControllerHandle to determine if the driver supports ControllerHandle. This function
may be called many times during platform initialization. In order to reduce boot times, the tests
performed by this function must be very small, and take as little time as possible to execute. This
function must not change the state of any hardware devices, and this function must be aware that the
device specified by ControllerHandle may already be managed by the same driver or a
different driver. This function must match its calls to AllocatePages() with FreePages(),
AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
Because ControllerHandle may have been previously started by the same driver, if a protocol is
already in the opened state, then it must not be closed with CloseProtocol(). This is required
to guarantee the state of ControllerHandle is not modified by this function.
@param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
@param[in] ControllerHandle The handle of the controller to test. This handle
must support a protocol interface that supplies
an I/O abstraction to the driver.
@param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This
parameter is ignored by device drivers, and is optional for bus
drivers. For bus drivers, if this parameter is not NULL, then
the bus driver must determine if the bus controller specified
by ControllerHandle and the child controller specified
by RemainingDevicePath are both supported by this
bus driver.
@retval EFI_SUCCESS The device specified by ControllerHandle and

Stops a device controller or a bus controller.
The Stop() function is designed to be invoked from the EFI boot service DisconnectController().
As a result, much of the error checking on the parameters to Stop() has been moved
into this common boot service. It is legal to call Stop() from other locations,
but the following calling restrictions must be followed, or the system behavior will not be deterministic.
1. ControllerHandle must be a valid EFI_HANDLE that was used on a previous call to this
same driver's Start() function.
2. The first NumberOfChildren handles of ChildHandleBuffer must all be a valid
EFI_HANDLE. In addition, all of these handles must have been created in this driver's
Start() function, and the Start() function must have called OpenProtocol() on
ControllerHandle with an Attribute of EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER.
@param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
@param[in] ControllerHandle A handle to the device being stopped. The handle must
support a bus specific I/O protocol for the driver
to use to stop the device.
@param[in] NumberOfChildren The number of child device handles in ChildHandleBuffer.
@param[in] ChildHandleBuffer An array of child handles to be freed. May be NULL
if NumberOfChildren is 0.
@retval EFI_SUCCESS The device was stopped.
@retval EFI_DEVICE_ERROR The device could not be stopped due to a device error.

Tests to see if this driver supports a given controller. If a child device is provided,
it further tests to see if this driver supports creating a handle for the specified child device.
This function checks to see if the driver specified by This supports the device specified by
ControllerHandle. Drivers will typically use the device path attached to
ControllerHandle and/or the services from the bus I/O abstraction attached to
ControllerHandle to determine if the driver supports ControllerHandle. This function
may be called many times during platform initialization. In order to reduce boot times, the tests
performed by this function must be very small, and take as little time as possible to execute. This
function must not change the state of any hardware devices, and this function must be aware that the
device specified by ControllerHandle may already be managed by the same driver or a
different driver. This function must match its calls to AllocatePages() with FreePages(),
AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
Because ControllerHandle may have been previously started by the same driver, if a protocol is
already in the opened state, then it must not be closed with CloseProtocol(). This is required
to guarantee the state of ControllerHandle is not modified by this function.
@param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
@param[in] ControllerHandle The handle of the controller to test. This handle
must support a protocol interface that supplies
an I/O abstraction to the driver.
@param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This
parameter is ignored by device drivers, and is optional for bus
drivers. For bus drivers, if this parameter is not NULL, then
the bus driver must determine if the bus controller specified
by ControllerHandle and the child controller specified
by RemainingDevicePath are both supported by this
bus driver.
@retval EFI_SUCCESS The device specified by ControllerHandle and
RemainingDevicePath is supported by the driver specified by This.
@retval EFI_ALREADY_STARTED The device specified by ControllerHandle and
RemainingDevicePath is already being managed by the driver
specified by This.
@retval EFI_ACCESS_DENIED The device specified by ControllerHandle and
RemainingDevicePath is already being managed by a different
driver or an application that requires exclusive access.

The Response() function queues an HTTP response to this HTTP instance, similar to

The HTTP driver will queue a receive token to the underlying TCP instance. When data
is received in the underlying TCP instance, the data will be parsed and Token will
be populated with the response data. If the data received from the remote host
contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting
(asynchronously) for more data to be sent from the remote host before signaling
Event in Token.
It is the responsibility of the caller to allocate a buffer for Body and specify the
size in BodyLength. If the remote host provides a response that contains a content
body, up to BodyLength bytes will be copied from the receive buffer into Body and
BodyLength will be updated with the amount of bytes received and copied to Body. This
allows the client to download a large file in chunks instead of into one contiguous
block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is
non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive
token to underlying TCP instance. If data arrives in the receive buffer, up to
BodyLength bytes of data will be copied to Body. The HTTP driver will then update
BodyLength with the amount of bytes received and copied to Body.
If the HTTP driver does not have an open underlying TCP connection with the host
specified in the response URL, Request() will return EFI_ACCESS_DENIED. This is

/**
This function is used to manage the headers portion of an HTTP message by providing
the ability to add, remove, or replace HTTP headers.
@param[in] SeedMessageSize Size in bytes of the initial HTTP header. This can be zero.
@param[in] SeedMessage Initial raw unformatted HTTP header to be used as a base for
building a new unformatted HTTP header. If NULL, SeedMessageSize
is ignored. The buffer containing this message will be allocated
and released by the caller.
@param[in] DeleteCount Number of null-terminated HTTP header field names in DeleteList.
@param[in] DeleteList List of null-terminated HTTP header field names to remove from SeedMessage.
Only the field names are in this list because the field values are irrelevant
to this operation. If NULL, DeleteCount is ignored. The buffer containing the
list will be allocated and released by the caller.
@param[in] AppendCount Number of header fields in AppendList.
@param[in] AppendList List of HTTP headers to populate NewMessage with. If SeedMessage is not NULL,
AppendList will be appended to the existing list from SeedMessage in NewMessage.
@param[out] NewMessageSize Pointer to the size in bytes of the new unformatted HTTP header in NewMessage.
@param[out] NewMessage Pointer to a new unformatted HTTP header. The storage for this NewMessage is
allocated by the driver publishing this protocol, and must be freed by the caller.
@retval EFI_SUCCESS Add, remove, and replace operations succeeded.
@retval EFI_OUT_OF_RESOURCES Could not allocate memory for NewMessage.
