       The tep_get_cpus() function gets the number of CPUs, which have a tracing buffer representing it. The tep
       argument is trace event parser context.

       The tep_set_cpus() function sets the number of CPUs, which have a tracing buffer representing it. The tep
       argument is trace event parser context. The cpu argument is the number of CPUs with tracing data.

           #include <event-parse.h>
           ...
           struct tep_handle *tep = tep_alloc();
           ...
                   tep_set_cpus(tep, 5);
           ...
                   printf("We have tracing data for %d CPUs", tep_get_cpus(tep));
