FID

Mode

Offset

FID (2 bytes): The File ID of the open file within which to seek.

Mode (2 bytes): The seek mode. Possible values are as follows.

Value

Meaning

0x0000

Seek from the start of the file.

0x0001

Seek from the current position.

0x0002

Seek from the end of the file.

The "current position" is the offset specified in a previous seek request, or the offset plus data length specified in a previous read or write request, whichever is most recent. The next successful read, write, or seek command changes the position of the file pointer.

Offset (4 bytes): A 32-bit signed long value indicating the file position, relative to the position indicated in Mode, to which to set the updated file pointer. The value of Offset ranges from -2 gigabytes to +2 gigabytes ((-2**31) to (2**31 -1) bytes).<30>
