1 /**   * \defgroup clock Clock interface   *   * The clock interface is the interface between the \ref timer "timer library"   * and the platform specific clock functionality. The clock   * interface must be implemented for each platform that uses the \ref   * timer "timer library".   *   * The clock interface does only one this: it measures time. The clock   * interface provides a macro, CLOCK_SECOND, which corresponds to one   * second of system time.   *   * \sa \ref timer "Timer library"   *   * @{   */  /*   * Copyright (c) 2004, Swedish Institute of Computer Science.   * All rights reserved.   *   * Redistribution and use in source and binary forms, with or without   * modification, are permitted provided that the following conditions   * are met:   * 1.
