Detailed Description

Provides a GUID and a data structure that can be used with EFI_FILE_PROTOCOL.GetInfo() or EFI_FILE_PROTOCOL.SetInfo() to get or set information about the system's volume.

This GUID is defined in UEFI specification.

◆ SIZE_OF_EFI_FILE_SYSTEM_INFO

#define SIZE_OF_EFI_FILE_SYSTEM_INFO   OFFSET_OF (EFI_FILE_SYSTEM_INFO, VolumeLabel)

The VolumeLabel field of the EFI_FILE_SYSTEM_INFO data structure is variable length.

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