Define Documentation

#define tscmp (  tvp, uvp, cmp   )

Value: (((tvp)->tv_sec == (uvp)->tv_sec) ? \ ((tvp)->tv_nsec cmp (uvp)->tv_nsec) : \ ((tvp)->tv_sec cmp (uvp)->tv_sec)) Compare two timespec's. Parameters: tvp  Pointer to the first timespec. uvp  Pointer to the second timespec. cmp  The comparison operator.

Function Documentation

struct timespec microsec_to_timespec (  unsigned long long  microseconds  )  [inline, static]

Convert a microsecond value to a struct timespec. Parameters: microseconds  The microsecond value to convert. Returns: A timespec that represents the given number of microseconds.

unsigned long long timespec_to_microsec (  struct timespec *  time_spec  )  [inline, static]

Convert a timespec to a microsecond value. NOTE: There is a loss of precision in the conversion. Parameters: time_spec  The timespec to convert. Returns: The number of microseconds specified by the timespec.
