Detailed Description

Timestamping operations for measuring the timing of CPU code.

Function Documentation

sleepMs()

void sleepMs ( uint64_t  milliseconds )

inline

Put the current thread to sleep for a specified number of milliseconds.

sleepNs()

void sleepNs ( uint64_t  nanoseconds )

inline

Put the current thread to sleep for a specified number of nanoseconds.

sleepTime() [1/2]

void sleepTime ( const timespec &  duration )

inline

Put the current thread to sleep for a specified time.

sleepTime() [2/2]

void sleepTime ( time_t  seconds, long int  nanoseconds  )

inline

Put the current thread to sleep for a specified time.

sleepUs()

void sleepUs ( uint64_t  microseconds )

inline

Put the current thread to sleep for a specified number of microseconds.

timeAdd()

timespec timeAdd ( const timespec &  a, const timespec &  b  )

inline

Add two times together.

timeCmp()

int timeCmp ( const timespec &  a, const timespec &  b  )

inline

Compare two timestamps.

Returns

0, if timestamp A equals timestamp B >0, if timestamp A is greater than timestamp B <0, if timestamp A is less than timestamp B

timeDiff() [1/2]

void timeDiff ( const timespec &  start, const timespec &  end, timespec *  result  )

inline

inline

Find the difference between two timestamps.

timeDouble()

float timeDouble ( const timespec &  a )

inline

Convert to 64-bit double (in milliseconds).

timeFloat()

float timeFloat ( const timespec &  a )

inline

Convert to 32-bit float (in milliseconds).

timeNew() [1/2]

timespec timeNew ( time_t  seconds, long int  nanoseconds  )

inline

Return an initialized timespec

timeNew() [2/2]

timespec timeNew ( long int  nanoseconds )

inline

Return an initialized timespec

timePrint()

void timePrint ( const timespec &  timestamp, const char *  text = NULL  )

inline

Print the time to stdout.

timestamp() [1/2]

void timestamp ( timespec *  timestampOut )

inline

Retrieve a timestamp of the current system time.

timestamp() [2/2]

inline

Produce a text representation of the timestamp.

timeZero()

timespec timeZero ( )

inline

Return a blank timespec that's been zero'd.
