Subject: [edk2-devel] [PATCH V1 3/3] SignedCapsulePkg: Update GetImage and GetImageInfo description details
Date: Thu, 14 Mar 2024 13:41:33 +0530	[thread overview]
Message-ID: <20240314081133.1134-3-madhan.pethaiyan@intel.com> (raw)
In-Reply-To: <20240314081133.1134-1-madhan.pethaiyan@intel.com>

1.For EFI_FIRMWARE_MANAGEMENT_PROTOCOL.GetImage():
Add the following sentence at the end of the Image parameter
description. "May be NULL with a zero ImageSize in order to determine
the size of the buffer needed".

Modify the description of "EFI_INVALID_PARAMETER" return code as "The
ImageSize is not too small and Image is NULL."

2.For EFI_FIRMWARE_MANAGEMENT_PROTOCOL.GetImageInfo():
Add the following sentence at the end of the ImageInfo parameter
description."May be NULL with a zero ImageInfoSize in order to
determine the size of the buffer needed".

Modify the description of "EFI_INVALID_PARAMETER" return code as "The
ImageInfoSize is not too small and Image is NULL." and add new
descriptions for "EFI_INVALID_PARAMETER" return code.
