GetOffset

The GetOffset method returns the offset of the focused value.

ODULong GetOffset ();

return value

The offset (in bytes) of the read/write position from the beginning of the data stream in the focused value, expressed as an unsigned 32-bit value.

DISCUSSION

An offset of 0 means the beginning of the data stream corresponding to the focused value; an offset equal to the size returned by the GetSize method means the end of the data stream.
