Why should your first program crash? You're not touching any memory you shouldn't, and one "ret" is as good as another as long as you've got the same size stack context, which you do to the last byte.

papi_get_multiplex
PAPI_get_multiplex(3) PAPI PAPI_get_multiplex(3)
NAME
PAPI_get_multiplex -
Get the multiplexing status of specified event set.
SYNOPSIS
Detailed Description
C Interface:
#include <papi.h>
int PAPI_get_multiplex( int EventSet );
Fortran Interface:
#include fpapi.h
PAPIF_get_multiplex( C_INT EventSet, C_INT check )
Parameters:
EventSet an integer handle for a PAPI event set as created by PAPI_create_eventset
Return values:
PAPI_OK
PAPI_EINVAL One or more of the arguments is invalid, or the EventSet is already multiplexed.
PAPI_ENOEVST The EventSet specified does not exist.
PAPI_EISRUN The EventSet is currently counting events.
PAPI_ENOMEM Insufficient memory to complete the operation.
PAPI_get_multiplex tests the state of the PAPI_MULTIPLEXING flag in the specified event set, returning TRUE if a PAPI event set is
multiplexed, or FALSE if not.
Example:
* int EventSet = PAPI_NULL;
* int ret;
*
* // Create an empty EventSet
* ret = PAPI_create_eventset(&EventSet);
* if (ret != PAPI_OK) handle_error(ret);
*
* // Bind it to the CPU component
* ret = PAPI_assign_eventset_component(EventSet, 0);
* if (ret != PAPI_OK) handle_error(ret);
*
* // Check current multiplex status
* ret = PAPI_get_multiplex(EventSet);
* if (ret == TRUE) printf("This event set is ready for multiplexing.")
* if (ret == FALSE) printf("This event set is not enabled for multiplexing.")
* if (ret < 0) handle_error(ret);
*
* // Turn on multiplexing
* ret = PAPI_set_multiplex(EventSet);
* if ((ret == PAPI_EINVAL) && (PAPI_get_multiplex(EventSet) == TRUE))
* printf("This event set already has multiplexing enabled0);
* else if (ret != PAPI_OK) handle_error(ret);
*
