Include dependency graph for coap_time.h:

This graph shows which files directly or indirectly include this file:

Macros
#define	COAP_TICKS_PER_SECOND ((coap_tick_t)(1000U))
	Use ms resolution on POSIX systems.

Typedefs
typedef uint64_t	coap_tick_t
	This data type represents internal timer ticks with COAP_TICKS_PER_SECOND resolution.

typedef time_t	coap_time_t
	CoAP time in seconds since epoch.

typedef int64_t	coap_tick_diff_t
	This data type is used to represent the difference between two clock_tick_t values.

Functions
void	coap_clock_init (void)
	Initializes the internal clock.

void	coap_ticks (coap_tick_t *t)
	Sets `t` to the internal time with COAP_TICKS_PER_SECOND resolution.

coap_time_t	coap_ticks_to_rt (coap_tick_t t)
	Helper function that converts coap ticks to wallclock time.

uint64_t	coap_ticks_to_rt_us (coap_tick_t t)
	Helper function that converts coap ticks to POSIX wallclock time in us.

coap_tick_t	coap_ticks_from_rt_us (uint64_t t)
	Helper function that converts POSIX wallclock time in us to coap ticks.

COAP_STATIC_INLINE int	coap_time_lt (coap_tick_t a, coap_tick_t b)
	Returns `1` if and only if `a` is less than `b` where less is defined on a signed data type.

COAP_STATIC_INLINE int	coap_time_le (coap_tick_t a, coap_tick_t b)
	Returns `1` if and only if `a` is less than or equal `b` where less is defined on a signed data type.
