SYNTAX
void rtapi_delay(long int _nsec_);
void rtapi_delay_max();ARGUMENTE
- nsec
-
Die gewünschte Verzögerungslänge in Nanosekunden.
BESCHREIBUNG
rtapi_delay is a simple delay. It is intended only for short delays, since it simply loops, wasting CPU cycles.
rtapi_delay_max returns the max delay permitted (usually approximately 1/4 of the clock period). Any call to rtapi_delay requesting a delay longer than the max will delay for the max time only.
rtapi_delay_max should be called before using rtapi_delay to make sure the required delays can be achieved. The actual resolution of the delay may be as good as one nano-second, or as bad as a several microseconds.
REALTIME CONSIDERATIONS
Kann von Init/Cleanup-Code und von Echtzeit-Tasks aus aufgerufen werden.
RETURN VALUE
rtapi_delay_max returns the maximum delay permitted.
