Function Documentation

WPI_GetSystemTime()

uint64_t WPI_GetSystemTime

(

void

)

Return the current system time in microseconds since the Unix epoch (January 1st, 1970 00:00 UTC).

Returns

Time in microseconds.

WPI_Now()

uint64_t WPI_Now

(

void

)

Return a value representing the current time in microseconds.

The epoch is not defined.

Returns

Time in microseconds.

WPI_NowDefault()

uint64_t WPI_NowDefault

(

void

)

The default implementation used for Now().

In general this is the time returned by the operating system.

Returns

Time in microseconds.

WPI_SetNowImpl()

void WPI_SetNowImpl

(

uint64_t(*)(void)

func

)

Set the implementation used by WPI_Now().

The implementation must return monotonic time in microseconds to maintain the contract of WPI_Now().

Parameters

func	Function called by WPI_Now() to return the time.
