Detailed Description

wrapper for a struct timespec, which nominally has nanosecond accuracy. On our IBM Debian linux boxen at least, timing accuracy appears to be roughly to the microsecond.

Examples:

profile_streams_thesis.cc, test_harness.cc, and test_hist.cc.

Member Function Documentation

bool Timeval::operator< (  const Timeval &  rhs  )  const

true if the left timestamp is before the right timestamp

bool Timeval::operator<= (  const Timeval &  rhs  )  const

true if the left timestamp is before or equal to the right timestamp

bool Timeval::operator== (  const Timeval &  rhs  )  const

true if the timestamps are equal, to the smallest resolution supported

bool Timeval::operator> (  const Timeval &  rhs  )  const

true if the left timestamp is after the right timestamp

bool Timeval::operator>= (  const Timeval &  rhs  )  const

true if the left timestamp is after or equal to the right timestamp
