Detailed Description
Function Documentation
◆ rtdm_clock_read()
| nanosecs_abs_t rtdm_clock_read | ( | void | ) |
Get system time.
- Returns
- The system time in nanoseconds is returned
- Note
- The resolution of this service depends on the system timer. In particular, if the system timer is running in periodic mode, the return value will be limited to multiples of the timer tick period.
- The system timer may have to be started to obtain valid results. Whether this happens automatically (as on Xenomai) or is controlled by the application depends on the RTDM host environment.
