NAME

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

SYNOPSIS

Detailed Description

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

       Parameters
           domain one of the following constants as defined in the papi.h header file

           • PAPI_DOM_USER User context counted
           • PAPI_DOM_KERNEL Kernel/OS context counted
           • PAPI_DOM_OTHER Exception/transient mode counted
           • PAPI_DOM_SUPERVISOR Supervisor/hypervisor context counted
           • PAPI_DOM_ALL All above contexts counted
           • PAPI_DOM_MIN The smallest available context
           • 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!\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);
