PAPI_set_domain (3) - Linux Manuals

NAME

PAPI_set_domain -

Set the default counting domain for new event sets bound to the cpu component.

SYNOPSIS

Detailed Description

@par C Prototype:
    #include <papi.h> @n
    int PAPI_set_domain( int domain );

@param domain one of the following constants as defined in the papi.h header file
@arg PAPI_DOM_USER User context counted
@arg PAPI_DOM_KERNEL  Kernel/OS context counted
@arg PAPI_DOM_OTHER Exception/transient mode counted
@arg PAPI_DOM_SUPERVISOR Supervisor/hypervisor context counted
@arg PAPI_DOM_ALL All above contexts counted
@arg PAPI_DOM_MIN The smallest available context
@arg PAPI_DOM_MAX The largest available context 

Return values:

PAPI_OK
PAPI_EINVAL One or more of the arguments is invalid.
 

PAPI_set_domain sets the default counting domain for all new event sets created by PAPI_create_eventset in all threads. This call implicitly sets the domain for the cpu component (component 0) and is included to preserve backward compatibility.

Example:

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!);
  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);
