Define Documentation

#define PTS_INIT_FAILURE (  _rate   )     (BUG_check (_rate, "PTS_initialize, unknown bus speed\n"), -1)

Compile selectable macro that either BUG checks on failure or returns -1 on failure. Parameters: _rate  The rate that cannot be translated

---

Function Documentation

unsigned int PTS_frequency (  void   )

Get the frequency of the PTS clock. Returns: The frequency, in Hertz, to the processor clock

int PTS_initialize (  void   )

Initializes the PTS facility. This is a one time only call to initialize internal data structures. This routine should be called as part of the library initialization sequence.

unsigned int PTS_nsecs_to_ptus (  unsigned int  nanoseconds  )

Convert a number of nanoseconds to PTUs. Parameters: nanoseconds  The number of nanoseconds to convert to PTUs Returns: The number of equivalent PTUs

unsigned int PTS_ptus_to_nsecs (  unsigned int  ptus  )

Convert a number of ptus to nanoseconds. Parameters: ptus  The number of PTUs to convert to nanoseconds Returns: The number of equivalent PTUs
