@par C Prototype:
    \#include <papi.h> @n
    int PAPI_set_cmp_domain( int domain, int  cidx );

@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 
@arg PAPI_DOM_HWSPEC Something other than CPU like stuff. Individual components can decode
low order bits for more meaning

@param cidx
    An integer identifier for a component. 
    By convention, component 0 is always the cpu component.

\fBPAPI_set_cmp_domain\fP sets the default counting domain for all new event sets in all threads, and requires an explicit component argument\&. Event sets that are already in existence are not affected\&. To change the domain of an existing event set, please see \fBPAPI_set_opt\fP\&. The reader should note that the domain of an event set affects only the mode in which the counter continues to run\&. Counts are still aggregated for the current process, and not for any other processes in the system\&. Thus when requesting PAPI_DOM_KERNEL , the user is asking for events that occur on behalf of the process, inside the kernel\&.

\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_cmp_domain(PAPI_DOM_KERNEL,0);
if (ret != PAPI_OK) handle_error(ret);
ret = PAPI_create_eventset(&EventSet);
if (ret != PAPI_OK) handle_error(ret);
