\fBPAPI_set_domain\fP sets the default counting domain for all new event sets created by \fBPAPI_create_eventset\fP in all threads\&. This call implicitly sets the domain for the cpu component (component 0) and is included to preserve backward compatibility\&.
.PP
\fBExample:\fP
.RS 4
.PP
.nf
int ret;
// Initialize the library
ret = PAPI_library_init(PAPI_VER_CURRENT);
if (ret > 0 && ret != PAPI_VER_CURRENT) {
fprintf(stderr,"PAPI library version mismatch!\\n");
exit(1);
}
if (ret < 0) handle_error(ret);
// Set the default domain for the cpu component
ret = PAPI_set_domain(PAPI_DOM_KERNEL);
if (ret != PAPI_OK) handle_error(ret);
ret = PAPI_create_eventset(&EventSet);
if (ret != PAPI_OK) handle_error(ret);
