PAPI_get_virt_nsec(3) PAPI PAPI_get_virt_nsec(3)NAME
PAPI_get_virt_nsec -
Get virtual time counter values in nanoseconds.
SYNOPSIS Detailed Description
Return values:
PAPI_ECNFLCT If there is no master event set. This will happen if the library has not been initialized, or for threaded applications,
if there has been no thread id function defined by the PAPI_thread_init function.
PAPI_ENOMEM For threaded applications, if there has not yet been any thread specific master event created for the current thread, and
if the allocation of such an event set fails, the call will return PAPI_ENOMEM or PAPI_ESYS .
This function returns the total number of virtual units from some arbitrary starting point. Virtual units accrue every time the process is
running in user-mode on behalf of the process. Like the real time counters, this count is guaranteed to exist on every platform PAPI
supports. However on some platforms, the resolution can be as bad as 1/Hz as defined by the operating system.

PAPI_add_named_event -
add PAPI preset or native hardware event by name to an EventSet
SYNOPSIS Detailed Description
@par C Interface:
int PAPI_add_named_event( int EventSet, char *EventName );
PAPI_add_named_event adds one event to a PAPI EventSet. @n
A hardware event can be either a PAPI preset or a native hardware event code.
For a list of PAPI preset events, see PAPI_presets or run the avail test case
in the PAPI distribution. PAPI presets can be passed to PAPI_query_event to see
if they exist on the underlying architecture.
For a list of native events available on current platform, run the papi_native_avail
utility in the PAPI distribution.
@param EventSet
An integer handle for a PAPI Event Set as created by PAPI_create_eventset.
@param EventCode
A defined event such as PAPI_TOT_INS.
@retval Positive-Integer
The number of consecutive elements that succeeded before the error.
@retval PAPI_EINVAL
One or more of the arguments is invalid.
@retval PAPI_ENOINIT
The PAPI library has not been initialized.
@retval PAPI_ENOMEM
Insufficient memory to complete the operation.
@retval PAPI_ENOEVST
The event set specified does not exist.
@retval PAPI_EISRUN
The event set is currently counting events.
@retval PAPI_ECNFLCT
The underlying counter hardware can not count this event and other events
in the event set simultaneously.
@retval PAPI_ENOEVNT
The PAPI preset is not available on the underlying hardware.
@retval PAPI_EBUG
Internal error, please send mail to the developers.
@par Examples:
* char EventName = "PAPI_TOT_INS";
* int EventSet = PAPI_NULL;
* unsigned int native = 0x0;
* if ( PAPI_create_eventset( &EventSet ) != PAPI_OK )
* handle_error( 1 );
* // Add Total Instructions Executed to our EventSet
* if ( PAPI_add_named_event( EventSet, EventName ) != PAPI_OK )
* handle_error( 1 );
* // Add native event PM_CYC to EventSet
* if ( PAPI_add_named_event( EventSet, "PM_CYC" ) != PAPI_OK )
* handle_error( 1 );
