/*

|
Get predefined boot options for platform.
|
||
|
|
|
||
|
|
@param[out] Count The number of elements in each of
|
||
|
|
BootOptions and BootKeys. On successful
|
||
|
|
return, Count is at least one.
|
||
|
|
|
||
|
|
@param[out] BootOptions An array of platform boot options.
|
||
|
|
BootOptions is pool-allocated by
|
||
|
|
GET_PLATFORM_BOOT_OPTIONS_AND_KEYS, and
|
||
|
|
GET_PLATFORM_BOOT_OPTIONS_AND_KEYS populates
|
||
|
|
every element in BootOptions with
|
||
|
|
EfiBootManagerInitializeLoadOption().
|
||
|
|
BootOptions shall not contain duplicate
|
||
|
|
entries. The caller is responsible for
|
||
|
|
releasing BootOptions after use with
|
||
|
|
EfiBootManagerFreeLoadOptions().
|
||
|
|
|
||
|
|
@param[out] BootKeys A pool-allocated array of platform boot
|
||
|
|
hotkeys. For every 0 <= Index < Count, if
|
||
|
|
BootOptions[Index] is not to be associated
|
||
|
|
with a hotkey, then BootKeys[Index] is
|
||
|
|
zero-filled. Otherwise, BootKeys[Index]
|
||
|
|
specifies the boot hotkey for
|
||
|
|
BootOptions[Index]. BootKeys shall not
|
||
|
|
contain duplicate entries (other than
|
||
|
|
zero-filled entries). The caller is
|
||
|
|
responsible for releasing BootKeys with
|
||
|
|
FreePool() after use.
|
||
|
|
|
||
|
|
@retval EFI_SUCCESS Count, BootOptions and BootKeys have
|
||
|
|
been set.

|
|
|

|
|
@retval EFI_OUT_OF_RESOURCES Memory allocation failed.
|
||
|
|

@retval EFI_UNSUPPORTED The platform doesn't provide boot options
|
||
|
|
as a feature.
|

|
|

|
@retval EFI_NOT_FOUND The platform could provide boot options
|

|
|
as a feature, but none have been
|

configured.
