Load File protocol as defined in the UEFI 2.0 specification.
|
|
|
|
The load file protocol exists to supports the addition of new boot devices,
|
|
and to support booting from devices that do not map well to file system.
|
|
Network boot is done via a LoadFile protocol.
|
|
|
|
UEFI 2.0 can boot from any device that produces a LoadFile protocol.

|
|
the size of Buffer required to retrieve the requested file.

@retval EFI_SUCCESS The file was loaded.

BufferSize is NULL.
|
|
@retval EFI_NO_MEDIA No medium was present to load the file.
|
|
@retval EFI_DEVICE_ERROR The file was not loaded due to a device error.

|
@retval EFI_NOT_FOUND The file was not found.
|
|
@retval EFI_ABORTED The file load process was manually cancelled.
|
|
@retval EFI_WARN_FILE_SYSTEM The resulting Buffer contains UEFI-compliant file system.
