Examples of java.nio.channels.FileChannel.position()

java.nio.channels.FileChannel.position()
Answers the current value of the file position pointer. @return the current position as a positive integer number of bytes fromthe start of the file. @throws ClosedChannelException if the channel is already closed. @throws IOException if some other IO problem occurs.
