Overview

FileGetInfo

EFI_STATUS
FileGetInfo (
  IN     EFI_FILE_PROTOCOL *File,
     OUT EFI_FILE_INFO     **Info
  );

基于 EFI_FILE_PROTOCOL 的 GetInfo

typedef
EFI_STATUS
(EFIAPI *EFI_FILE_GET_INFO)(
  IN EFI_FILE_PROTOCOL        *This,
  IN EFI_GUID                 *InformationType,
  IN OUT UINTN                *BufferSize,
  OUT VOID                    *Buffer
  );

对于InformationType,有gEfiFileInfoGuid / gEfiFileSystemInfoGuid

我们这里用前者.

• Guid/FileInfo.h
• src/boot/SigmaBootPkg/Boot.inf

[Guids]
    gEfiFileInfoGuid
