Examples of ucar.unidata.io.RandomAccessFile.skipBytes()

ucar.unidata.io.RandomAccessFile.skipBytes()
Skips exactly n bytes of input. This method blocks until all the bytes are skipped, the end of the stream is detected, or an exception is thrown. @param n the number of bytes to be skipped. @return the number of bytes skipped, which is always n. @throws EOFException if this file reaches the end before skippingall the bytes. @throws IOException if an I/O error occurs.
