SuperCore Timestamps may be used to * represent time of day, uptime, or intervals. * * The key attribute of the SuperCore Timestamp handler is that it * is a completely opaque handler. There can be multiple implementations * of the required functionality and with a recompile, RTEMS can use * any implementation. It is intended to be a simple wrapper. * * This handler can be implemented as either struct timespec or * unsigned64 bit numbers. The use of a wrapper class allows the * the implementation of timestamps to change on a per architecture * basis. This is an important option as the performance of this * handler is critical. * * @{ */ #include #ifdef __cplusplus extern "C" { #endif /** * Define the Timestamp control type. */ typedef int64_t Timestamp_Control; #ifdef __cplusplus } #endif /** @} */ #endif /* end of include file */
