cpu time VS. calendar time

cpu time VS. calendar time

[Todd Thompson]

We are trying to find out how much cpu time a procedure or function call
takes.  We've found the calendar package with function clock.  Is there an
equivilant which will give me cpu time?  TIA.

The LRM does not call out a standard package for retrieving CPU time. 
Retrieving CPU time is therefore system dependent, and is probably best
done through the use of pragma interface. I have written a package with a 
portable specification that gives simple CPU times.
I have Unix and PC versions; the Unix version uses pragma interface and
a little C program to get the CPU time. I can send this to anyone who
wishes it; let me know by e-mail. If there is a lot of interest, I will
post it.
