99 @param[in] Private The pointer to the driver's private data.
100 @param[in] HeaderOnly Only request the response header, it could save a lot of time if
101 the caller only want to know the size of the requested file.
102 @param[in, out] BufferSize On input the size of Buffer in bytes. On output with a return
103 code of EFI_SUCCESS, the amount of data transferred to
104 Buffer. On output with a return code of EFI_BUFFER_TOO_SMALL,
105 the size of Buffer required to retrieve the requested file.
106 @param[out] Buffer The memory buffer to transfer the file to. IF Buffer is NULL,
107 then the size of the requested file is returned in
109 @param[out] ImageType The image type of the downloaded file.
