Measuring the CPU utilization of a C program

I need to measure the CPU utilization of a C program running in a CICS address space. I know that I cannot use clock(). What can I use instead? We do not have Omegamon or Strobe. Thanks.

The easiest way to do this measurement will be to turn on CICS' monitoring and stats functions and then do the analysis of the SMF records offline.

If you are just getting into this type of performance monitoring: you might care to look at the recent CICS tools announcement wherein is a new utility called the Performance Analyzer which will probably do what you need with a fairly minimal manual effort.
