/** * \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.
