Function Documentation

int mbedtls_timing_get_delay

(

void *

data

)

Get the status of delays (Memory helper: number of delays passed.)

Parameters

data	Pointer to timing data Must point to a valid mbedtls_timing_delay_context struct.

Returns

-1 if cancelled (fin_ms = 0), 0 if none of the delays are passed, 1 if only the intermediate delay is passed, 2 if the final delay is passed.

unsigned long mbedtls_timing_get_timer	(	struct mbedtls_timing_hr_time *	val,
		int	reset
	)

void mbedtls_timing_set_delay	(	void *	data,
		uint32_t	int_ms,
		uint32_t	fin_ms
	)

Set a pair of delays to watch (See mbedtls_timing_get_delay().)

Parameters

data	Pointer to timing data. Must point to a valid mbedtls_timing_delay_context struct.
int_ms	First (intermediate) delay in milliseconds. The effect if int_ms > fin_ms is unspecified.
fin_ms	Second (final) delay in milliseconds. Pass 0 to cancel the current delay.

Note

To set a single delay, either use mbedtls_timing_set_timer directly or use this function with int_ms == fin_ms.
