tep_get_cpus, tep_set_cpus - Get / set the number of CPUs, which have a tracing buffer representing it. Note, the buffer may be empty.
#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.
#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));
event-parse.h Header file to include in order to have access to the library APIs. -ltraceevent Linker switch to add when building a program that uses the library.
