+*#include <event-parse.h>*
+
+int *tep_get_cpus*(struct tep_handle pass:[*]_tep_);
+void *tep_set_cpus*(struct tep_handle pass:[*]_tep_, int _cpus_);
+--
+
+DESCRIPTION
+-----------
+The _tep_get_cpus()_ functions gets the number of CPUs, which have tracing 
+data recorded. The _tep_ argument is trace event parser context.

+The _tep_set_cpus()_ functions sets the number of CPUs, which have tracing 
+data recorded. The _tep_ argument is trace event parser context. The _cpu_
+argument is the number of CPUs with tracing data. This information is saved 
+in the trace.dat file.
+

+#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));
