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); * See Also: PAPI_multiplex_init PAPI_set_opt PAPI_create_eventset Author Generated automatically by Doxygen for PAPI from the source code.

NAME
PAPI_reset - Reset the hardware event counts in an event set. SYNOPSIS
Detailed Description @par C Prototype: int PAPI_reset( int EventSet ); @param EventSet an integer handle for a PAPI event set as created by PAPI_create_eventset @retval PAPI_OK @retval PAPI_ESYS A system or C library call failed inside PAPI, see the errno variable. @retval PAPI_ENOEVST The EventSet specified does not exist. PAPI_reset() zeroes the values of the counters contained in EventSet. This call assumes an initialized PAPI library and a properly added event set @par Example: int EventSet = PAPI_NULL; int Events[] = {PAPI_TOT_INS, PAPI_FP_OPS}; int ret; // Create an empty EventSet ret = PAPI_create_eventset(&EventSet); if (ret != PAPI_OK) handle_error(ret); // Add two events to our EventSet ret = PAPI_add_events(EventSet, Events, 2); if (ret != PAPI_OK) handle_error(ret); // Start counting ret = PAPI_start(EventSet); if (ret != PAPI_OK) handle_error(ret); // Stop counting, ignore values ret = PAPI_stop(EventSet, NULL); if (ret != PAPI_OK) handle_error(ret); // reset the counters in this EventSet ret = PAPI_reset(EventSet); if (ret != PAPI_OK) handle_error(ret); * See Also: PAPI_create_eventset Author Generated automatically by Doxygen for PAPI from the source code.
