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-bit
MCLOCK8 will return a 32-bit value, even though it is converted to a 64-bit
INTEGER(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.
RESULT = MCLOCK8()
The return value is a scalar of type
INTEGER(8), equal to the number of clock ticks since the start of the process, or
-1 if the system does not support
