Offset

Offset (4 bytes): A 32-bit unsigned value indicating the absolute file position relative to the start of the file at which the file pointer is currently set. The value of Offset ranges from 0 to 4 gigabytes (0 to 2**32 - 1 bytes).

A seek that results in a file position value that cannot be expressed in 32 bits MUST set Offset to the least significant 32 bits.<31>

ByteCount

ByteCount (2 bytes): This field MUST be 0x0000. No data is sent by this message.

The response returns the new file pointer in Offset, expressed as the number of bytes from the start of the file. The Offset MAY be beyond the current end of file. An attempt to seek to before the start of file sets the current file pointer to the start of the file (0x00000000).
