EFI_FILE_INFO_ID

#define EFI_FILE_INFO_ID

Value:

  { \
    0x9576e92, 0x6d3f, 0x11d2, {0x8e, 0x39, 0x0, 0xa0, 0xc9, 0x69, 0x72, 0x3b } \

SIZE_OF_EFI_FILE_INFO

#define SIZE_OF_EFI_FILE_INFO   OFFSET_OF (EFI_FILE_INFO, FileName)

The FileName field of the EFI_FILE_INFO data structure is variable length. Whenever code needs to know the size of the EFI_FILE_INFO data structure, it needs to be the size of the data structure without the FileName field. The following macro computes this size correctly no matter how big the FileName array is declared. This is required to make the EFI_FILE_INFO data structure ANSI compilant.
