\fBPAPI_event_code_to_name\fP is used to translate a 32-bit integer PAPI event code into an ASCII PAPI event name\&. Either Preset event codes or Native event codes can be passed to this routine\&. Native event codes and names differ from platform to platform\&.
.PP
\fBParameters\fP
.RS 4
\fIEventCode\fP The numeric code for the event\&.
.br
\fI*EventName\fP A string containing the event name as listed in PAPI_presets or discussed in PAPI_native\&.
.RE
.PP
\fBReturn values\fP
.RS 4
\fIPAPI_EINVAL\fP One or more of the arguments is invalid\&.
.br
\fIPAPI_ENOTPRESET\fP The hardware event specified is not a valid PAPI preset\&.
.br
\fIPAPI_ENOEVNT\fP The hardware event is not available on the underlying hardware\&.
