get_cycles function has return type unsigned long long and returns the value of Time Stamp Counter Register
Precisely
get_cycles— The resolution of get_cycles is various. The get_cycles function, which is defined all on platforms, returns a count of system clock cycles that fit into a single CPU register. Typically this is the lower half of the two 32-bit counters mentioned previously. If the processor doesn't contain a clock counter, get_cycles returns 0. get_cycles returns 0 on 486 and ARM processors.
