buffer representing it. Note, the buffer may be empty.

SYNOPSIS
--------

--
*#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()* 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
-------
[source,c]
--
#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));
