tep_get_cpus - Man Page

#include <event-parse​.h>

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

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​.

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