# PAPI\_stop(3)

Stop counting hardware events in an event set.

## NAME

PAPI\_stop - Stop counting hardware events in an event set.

## SYNOPSIS

## Detailed Description

**C Interface:**

\#include \<**papi.h**\> \
\
  int **PAPI\_stop( int  EventSet, long long \* values )**;

**Parameters**

*EventSet* -- an integer handle for a PAPI event set as created by **PAPI\_create\_eventset** \
 *values* -- an array to hold the counter values of the counting events

**Return values**

*PAPI\_OK* \
 *PAPI\_EINVAL* One or more of the arguments is invalid. \
 *PAPI\_ESYS* A system or C library call failed inside PAPI, see the errno variable. \
 *PAPI\_ENOEVST* The EventSet specified does not exist. \
 *PAPI\_ENOTRUN* The EventSet is currently not running.

**PAPI\_stop** halts the counting of a previously defined event set and the counter values contained in that EventSet are copied into the values array Assumes an initialized PAPI library and a properly added event set.

**Example:**

```
int EventSet = PAPI_NULL;
long long values[2];
int ret;
ret = PAPI_create_eventset(&EventSet);
if (ret != PAPI_OK) handle_error(ret);
// Add Total Instructions Executed to our EventSet
ret = PAPI_add_event(EventSet, PAPI_TOT_INS);
if (ret != PAPI_OK) handle_error(ret);
// Start counting
ret = PAPI_start(EventSet);
if (ret != PAPI_OK) handle_error(ret);
poorly_tuned_function();
ret = PAPI_stop(EventSet, values);
if (ret != PAPI_OK) handle_error(ret);
printf("%lld\\n",values[0]);
```
