Detailed Description

The clock library is the interface between Contiki and the platform specific clock functionality. The clock library performs a single function: measuring time. Additionally, the clock library provides a macro, CLOCK_SECOND, which corresponds to one second of system time.

Note: The clock library need in many cases not be used directly. Rather, the timer library or the event timers should be used.

Macro Definition Documentation

◆ CLOCK_SECOND

#define CLOCK_SECOND

A second, measured in system clock time.

Function Documentation

◆ clock_delay()

void clock_delay ( unsigned int d )

This is a asynchronous delay function.

Attention: Due to UNIFY running in the same thread as Z-Wave protocol, a vTaskDelay() was not a good idea and this function is now returning immediately. No delays are allowed.

Parameters

d	Delay in seconds.

◆ clock_fine()

unsigned short clock_fine ( void )

◆ clock_fine_max()

int clock_fine_max ( void )

◆ clock_init()

void clock_init ( void )

Initialize the clock library.

This function initializes the clock library and should be called from the main() function of the system.

◆ clock_lte()

int clock_lte	(	clock_time_t	t1,
		clock_time_t	t2
	)

Check if clock time t1 is less than or equal to clock time t2.

Since clock_time_t may be an unsigned type, use this function for comparison.

See also: E.g., IETF RFC 1982 https://tools.ietf.org/rfc/rfc1982.txt.

Return value is greater than 0 if t1 is equal to t2 or if t1 is less than t2 (modulo max clock_time).

◆ clock_seconds()

CCIF unsigned long clock_seconds ( void )

◆ clock_time()

CCIF clock_time_t clock_time ( void )

Get the current clock time.

This function returns the current system clock time.

Returns: The current clock time, measured in system ticks.
