diffTime
fills an internal Time
structure with the
difference in times between two passed Time
structures (
end
- start
). The internal structure will be
overwritten by the next call to diffTime
. If the diff
argument is not NULL
, the difference data are copied there as
well.
It returns a pointer to the internal Time
structure upon success.
If either of start
or end
are NULL
, it returns
NULL
.
