tep_get_cpus3

Usage

#include <event-parse.h>
int tep_get_cpus(struct tep_handle *tep);
void tep_set_cpus(struct tep_handle *tep, int cpus);

Overview

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.

Examples

#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));
