		IN BOOLEAN	ForceVersionMatch,
		OUT UINT32 *	LastAttemptVersion,
		OUT UINT32 *	LastAttemptStatus,
		OUT VOID **	AuthenticatedImage,
		OUT UINTN *	AuthenticatedImageSize
	)

Authenticated system firmware FMP capsule image.

Caution: This function may receive untrusted input.

Parameters

[in]	Image	The FMP capsule image, including EFI_FIRMWARE_IMAGE_AUTHENTICATION.
[in]	ImageSize	The size of FMP capsule image in bytes.
[in]	ForceVersionMatch	TRUE: The version of capsule must be as same as the version of current image. FALSE: The version of capsule must be as same as greater than the lowest supported version of current image.
[out]	LastAttemptVersion	The last attempt version, which will be recorded in ESRT and FMP EFI_FIRMWARE_IMAGE_DESCRIPTOR.
[out]	LastAttemptStatus	The last attempt status, which will be recorded in ESRT and FMP EFI_FIRMWARE_IMAGE_DESCRIPTOR.
[out]	AuthenticatedImage	The authenticated capsule image, excluding EFI_FIRMWARE_IMAGE_AUTHENTICATION.
[out]	AuthenticatedImageSize	The size of the authenticated capsule image in bytes.

Return values

TRUE	Authentication passes and the authenticated image is extracted.
FALSE	Authentication fails and the authenticated image is not extracted.
