NAMEPAPI_get_event_info − get the event's name and description info

---

SYNOPSISC Interface #include <papi.h> int PAPI_get_event_info(int EventCode, PAPI_event_info_t *info);Fortran Interface #include "fpapi.h" PAPIF_get_event_info(C_INT EventCode, C_STRING symbol, C_STRING long_descr, C_STRING short_descr, C_INT count, C_STRING event_note, C_INT flags,, C_INT check)

---

DESCRIPTIONIn C, this function fills the event information into a structure. In Fortran, some fields of the structure are returned explicitly. This function works with existing PAPI preset and native event codes.

---

ARGUMENTSThe following arguments are implicit in the structure returned by the C function, or explicitly returned by Fortran. EventCode -- event code(preset or native) info -- structure with the event information symbol -- whether the preset is part of the API long_descr -- detail description about the event short_descr -- short description about the event event_note -- notes about the event

---

RETURN VALUESOn success, the C function returns PAPI_OK, and the Fortran function returns PAPI_OK.
 On error, a non-zero error code is returned by the function.

---

ERRORSPAPI_EINVAL"  One or more of the arguments is invalid. PAPI_ENOTPRESET"  The PAPI preset mask was set, but the hardware event specified is not a valid PAPI preset. PAPI_ENOEVNT"  The PAPI preset is not available on the underlying hardware.

---

EXAMPLE/*Find the event code for PAPI_TOT_INS and its info*/ PAPI_event_name_to_code("PAPI_TOT_INS",&EventCode) if (PAPI_get_event_info(EventCode, &info) == PAPI_OK) handle_error(1);

---

BUGSThis function has no known bugs.
