#include <\fBpapi\&.h\fP> 
.br
 int \fBPAPI_stop( int  EventSet, long long * values )\fP;
.RE
.PP
\fBParameters:\fP
.RS 4
\fIEventSet\fP -- an integer handle for a PAPI event set as created by \fBPAPI_create_eventset\fP 
.br
\fIvalues\fP -- an array to hold the counter values of the counting events
.RE
.PP
\fBReturn values:\fP
.RS 4
\fIPAPI_OK\fP 
.br
\fIPAPI_EINVAL\fP One or more of the arguments is invalid\&. 
.br
\fIPAPI_ESYS\fP A system or C library call failed inside PAPI, see the errno variable\&. 
.br
\fIPAPI_ENOEVST\fP The EventSet specified does not exist\&. 
.br
\fIPAPI_ENOTRUN\fP The EventSet is currently not running\&.
.RE
.PP
\fBPAPI_stop\fP 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\&.
.PP
\fBExample:\fP
.RS 4

.PP
.nf
*  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]);
