Skips over and discards n bytes of data from this input stream. The skip method may, for a variety of reasons,
end up skipping over some smaller number of bytes, possibly 0. This may result from any of a number of
conditions; reaching end of file before n bytes have been skipped is only one possibility. The actual number of
bytes skipped is returned. If n is negative, no bytes are skipped.

Note repositioning the file read stream will disable file MD5 checking.

@param n
A <code>long</code> which represents the number of bytes to skip.
