Preparing your program for profiling

To use either of the profilers that are supplied with the C compilation system, you must do two things:

1. Compile and link your program with a profiling option:
   
   for prof: cc -qp test.c
   for lprof: cc -ql test.c

2. Run the profiled program:

   $ a.out
   

where prog is the name of the profiled program. The data files are inputs to the profilers. See ``lprof'' and ``Interpreting profiling output'' in Chapter 9, ``C programmer's productivity tools'' for further information.
