PAPI_remove_named_event(3)

NAME
PAPI_remove_named_event -

removes a named hardware event from a PAPI event set.

SYNOPSIS

Detailed Description

A hardware event can be either a PAPI Preset or a native hardware event code. For a list of PAPI preset events, see PAPI_presets or run the papi_avail utility in the PAPI distribution. PAPI Presets can be passed to PAPI_query_event to see if they exist on the underlying architecture. For a list of native events available on the current platform, run papi_native_avail in the PAPI distribution.

C Interface:
    #include <papi.h>
     int PAPI_remove_event( int EventSet, int EventCode );

Parameters:
    EventSet -- an integer handle for a PAPI event set as created by PAPI_create_eventset
    EventName -- a defined event such as PAPI_TOT_INS or a native event.

Return values:
    PAPI_OK Everything worked.
    PAPI_EINVAL One or more of the arguments is invalid.
    PAPI_ENOINIT The PAPI library has not been initialized.
    PAPI_ENOEVST The EventSet specified does not exist.
    PAPI_EISRUN The EventSet is currently counting events.
    PAPI_ECNFLCT The underlying counter hardware can not count this event and other events in the EventSet simultaneously.
    PAPI_ENOEVNT The PAPI preset is not available on the underlying hardware.

Example:

       char EventName = 'PAPI_TOT_INS';
       int EventSet = PAPI_NULL;
       int ret;
       // Create an empty EventSet
       ret = PAPI_create_eventset(&EventSet);
       if (ret != PAPI_OK) handle_error(ret);
       // Add Total Instructions Executed to our EventSet
       ret = PAPI_add_named_event(EventSet, EventName);
       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);
       // Remove event
       ret = PAPI_remove_named_event(EventSet, EventName);
       if (ret != PAPI_OK) handle_error(ret);
