9.185. MCLOCK8
9.185 MCLOCK8 — Time function (64-bit)
- Description:
- Returns the number of clock ticks since the start of the process, based on the function
clock(3)
in the C standard library.Warning: this intrinsic does not increase the range of the timing values over that returned by
clock(3)
. On a system with a 32-bitclock(3)
,MCLOCK8
will return a 32-bit value, even though it is converted to a 64-bitINTEGER(8)
value. That means overflows of the 32-bit value can still occur. Therefore, the values returned by this intrinsic might be or become negative or numerically less than previous values during a single run of the compiled program. - Standard:
- GNU extension
- Class:
- Function
