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));
