#include <\fBpapi\&.h\fP>
.br
int PAPI_stop( int EventSet, long long * values );
.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]);
