typedef
EFI_STATUS
UninstallMultipleProtocolInterfaces (
IN EFI_HANDLE Handle,
...
);
Parameters
Handle The handle to remove the protocol interfaces from.
... A variable argument list containing pairs of protocol GUIDs and
protocol interfaces.
Description
This function removes a set of protocol interfaces from the boot services environment. It removes
arguments from the variable argument list in pairs. The first item is always a pointer to the
protocol’s GUID, and the second item is always a pointer to the protocol’s interface. These pairs
are used to call the boot service UninstallProtocolInterface()
to remove a protocol
interface from Handle. The pairs of arguments are removed in order from the variable argument
list until a NULL protocol GUID value is found. If all of the protocols are uninstalled from
Handle,thenEFI_SUCCESS is returned. If any errors are generated while the protocol
interfaces are being uninstalled, then the protocols uninstalled prior to the error will be reinstalled
with the boot service InstallProtocolInterface()
and the status code
EFI_INVALID_PARAMETER is returned.
Status Codes Returned
EFI_SUCCESS All the protocol interfaces were removed.
EFI_INVALID_PARAMETER One of the protocol interfaces was not previously installed on
Handle.
