MCLOCK8(3f)

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-bit clock(3), 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.

STANDARD
GNU extension

CLASS
Function

SYNTAX
RESULT = MCLOCK8()

RETURN VALUE
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 clock(3).
