void mbedtls_set_alarm | ( | int | seconds | ) |
Setup an alarm clock.
seconds | delay before the "mbedtls_timing_alarmed" flag is set |
int mbedtls_timing_get_delay | ( | void * | data | ) |
Get the status of delays (Memory helper: number of delays passed.)
data | Pointer to timing data Must point to a valid mbetls_timing_delay_context struct. |
unsigned long mbedtls_timing_get_timer | ( | struct mbedtls_timing_hr_time * | val, |
int | reset | ||
) |
Return the elapsed time in milliseconds.
val | points to a timer structure |
reset | if set to 1, the timer is restarted |
unsigned long mbedtls_timing_hardclock | ( | void | ) |
Return the CPU cycle counter value.
int mbedtls_timing_self_test | ( | int | verbose | ) |
Checkup routine.
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()
.)
data | Pointer to timing data Must point to a valid mbetls_timing_delay_context struct. |
int_ms | First (intermediate) delay in milliseconds. |
fin_ms | Second (final) delay in milliseconds. Pass 0 to cancel the current delay. |
