This library retrieves pointers to the UEFI HII Protocol instances in the
|
|
library's constructor. All of the UEFI HII related protocols are optional,
|
|
so the consumers of this library class must verify that the global variable
|
|
pointers are not NULL before use.

The constructor function retrieves pointers to the UEFI HII protocol instances
|
|
|
|
The constructor function retrieves pointers to the four UEFI HII protocols from the
|
|
handle database. These include the UEFI HII Font Protocol, the UEFI HII String
|
|
Protocol, the UEFI HII Image Protocol, the UEFI HII Database Protocol, and the
|
|
UEFI HII Config Routing Protocol. This function always return EFI_SUCCESS.
|
|
All of these protocols are optional if the platform does not support configuration
|
|
and the UEFI HII Image Protocol and the UEFI HII Font Protocol are optional if
|
|
the platform does not support a graphical console. As a result, the consumers
|
|
of this library much check the protocol pointers againt NULL before using them,
|
|
or use dependency expressions to guarantee that some of them are present before
|
|
assuming they are not NULL.
|
|
|
|
@param ImageHandle The firmware allocated handle for the EFI image.
|
|
@param SystemTable A pointer to the EFI System Table.
|
|
|
|
@retval EFI_SUCCESS The constructor always returns EFI_SUCCESS.
