cpu_time = %CPUTIME
Return value
cpu_time
The CPU time accumulated by the current process. The returned value represents the number of 10 millisecond intervals (tics) accumulated. (i)
Discussion
%CPUTIME is evaluated at runtime. It is functionally equivalent to the CPUTM subroutine, but we recommend you use %CPUTIME because functions are, generally speaking, more efficient than subroutines.
On Windows, the time is elapsed time, not accumulated system time.
On UNIX, the CPU time accumulated includes CPU time for all child processes that the runtime waits for (for example, XCALL SPAWN and XCALL SHELL, but not XCALL RUNJB).
CPU time is accumulated for an entire process, not for a program or programs within the process.
The CPU time is not zeroed out at the beginning of a Synergy program. To measure the CPU time consumed by a program, you must sample the CPU time at program startup and again at the checkpoint, and then subtract the first value from the second.
Examples
The following example measures the time consumed by the “doit” routine.
record last ,i4 now ,i4 proc xcall flags(1001010, 1) open(1, o, "TT:") last = %cputime ; Get the time at startup xcall doit ; Do some processing here now = %cputime ; Get the time at the end writes(1, "Elapsed time = " + %string(now - last)) close 1 stop end
