The
clock ();
function
determines the amount of processor time used since the invocation of the
calling process, measured in
CLOCKS_PER_SEC s
of a second.
RETURN VALUES
The
clock ();
function returns the amount of time used unless an error occurs, in which
case the return value is -1.
The
clock ();
function conforms to
St -isoC .
However,
St -susv2
requires
CLOCKS_PER_SEC
to be defined as one million.
Fx does not conform to this requirement;
changing the value would introduce binary incompatibility
and one million is still inadequate on modern processors.
