Empty and destroy an EventSet. More...

Detailed Description

C Interface:: #include <papi.h>
int PAPI_destroy_eventset( int * EventSet );

PAPI_destroy_eventset deallocates the memory associated with an empty PAPI EventSet.

Parameters:

*EventSet A pointer to the integer handle for a PAPI event set as created by PAPI_create_eventset. The value pointed to by EventSet is then set to PAPI_NULL on success.

Return values:

PAPI_EINVAL	One or more of the arguments is invalid. Attempting to destroy a non-empty event set or passing in a null pointer to be destroyed.
PAPI_ENOEVST	The EventSet specified does not exist.
PAPI_EISRUN	The EventSet is currently counting events.
PAPI_EBUG	Internal error, send mail to ptools-perfapi@ptools.org and complain.

Examples:

    // Free all memory and data structures, EventSet must be empty.
    if ( PAPI_destroy_eventset( &EventSet ) != PAPI_OK )
    handle_error( 1 );

Bug:: If the user has set profile on an event with the call, then when destroying the EventSet the memory allocated by will not be freed. The user should turn off profiling on the Events before destroying the EventSet to prevent this behavior.
