mx_ticks_per_second

NAME

ticks_per_second - Read the number of high-precision timer ticks in a second.

SYNOPSIS

#include <magenta/syscalls.h>

uint64_t mx_ticks_per_second(void)

DESCRIPTION

mx_ticks_per_second() returns the number of high-precision timer ticks in a second.

This can be used together with mx_ticks_get() to calculate the amount of time elapsed between two subsequent calls to mx_ticks_get().

RETURN VALUE

mx_ticks_per_second() returns the number of high-precision timer ticks in a second.

ERRORS

mx_ticks_per_second() does not report any error conditions.

EXAMPLES

uint64_t ticks_per_second = mx_ticks_per_second();
uint64_t ticks_start = mx_ticks_get();

// do some more work

uint64_t ticks_end = mx_ticks_get();
double elapsed_seconds = (ticks_end - ticks_start) / (double)ticks_per_second;
