NAME
       tep_get_cpus, tep_set_cpus - Get / set the number of CPUs, which have a
       tracing buffer representing it. Note, the buffer may be empty.

SYNOPSIS
       #include <event-parse.h>

       int tep_get_cpus(struct tep_handle *tep);
       void tep_set_cpus(struct tep_handle *tep, int cpus);

DESCRIPTION
       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.

RETURN VALUE
       The tep_get_cpus() functions returns the number of CPUs, which have
       tracing data recorded.

EXAMPLE
           #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));
