ANSI Common Lisp 25 Environment 25.2 Dictionary of Environment
< no arguments >
- Arguments and Values:
internal-time - a non-negative integer.
Returns as an integer the current
run time in internal time units. The precise meaning of this quantity is
implementation-defined; it may measure real time, run time, CPU cycles, or some
other quantity. The intent is that the difference between the values of two calls
to this function be the amount of time between the two calls during which
computational effort was expended on behalf of the executing program.
- Affected By:
the time of day (i.e., the passage of time).
- See Also:
Depending on the implementation, paging time and garbage
collection time might be included in this measurement. Also, in a
multitasking environment, it might not be possible to show the time for
just the running process, so in some implementations, time taken
by other processes during the same time interval might be included in
this measurement as well.
