Examples of java.io.DataInputStream.skip()

java.io.DataInputStream.skip()
Skips over and discards n bytes of data from the input stream. The skip method may, for a variety of reasons, end up skipping over some smaller number of bytes, possibly 0. The actual number of bytes skipped is returned.
This method simply performs in.skip(n). @param n the number of bytes to be skipped. @return the actual number of bytes skipped. @exception IOException if an I/O error occurs.
