Routine Description:
|
||||
Causes the driver to load a specified file.
|
||||
|
||||
Arguments:
|
||||
This - Protocol instance pointer.
|
||||
FilePath - The device specific path of the file to load.
|
||||
BootPolicy - Should always be FALSE.
|
||||
BufferSize - On input the size of Buffer in bytes. On output with a return
|
||||
code of EFI_SUCCESS, the amount of data transferred to
|
||||
Buffer. On output with a return code of EFI_BUFFER_TOO_SMALL,
|
||||
the size of Buffer required to retrieve the requested file.
|
||||
Buffer - The memory buffer to transfer the file to. IF Buffer is NULL,
|
||||
then no the size of the requested file is returned in
|
||||
BufferSize.
|
||||
|
||||
Returns:
|
||||
EFI_SUCCESS - The file was loaded.
|
||||
EFI_UNSUPPORTED - BootPolicy is TRUE.
|
||||
EFI_INVALID_PARAMETER - FilePath is not a valid device path, or
|
||||
BufferSize is NULL.
|
||||
EFI_NO_MEDIA - No medium was present to load the file.
|
||||
EFI_DEVICE_ERROR - The file was not loaded due to a device error.
|
||||
EFI_NO_RESPONSE - The remote system did not respond.
|
||||
EFI_NOT_FOUND - The file was not found
|
||||
EFI_ABORTED - The file load process was manually cancelled.
|
||||
EFI_BUFFER_TOO_SMALL - The BufferSize is too small to read the current
|
||||
directory entry. BufferSize has been updated with
|
||||
the size needed to complete the request.
