Sets this channel's position.
Setting the position to a value that is greater than the current size is legal but does not change the size of the entity. A later attempt to read bytes at such a position will immediately return an end-of-file indication. A later attempt to write bytes at such a position will cause the entity to grow to accommodate the new bytes; the values of any bytes between the previous end-of-file and the newly-written bytes are unspecified.
Setting the channel's position is not recommended when connected to
an entity, typically a file, that is opened with the APPEND option. When opened for
append, the position is first advanced to the end before writing.
