.SH "Detailed Description"
.PP 
List the events in an event set\&.
.PP
\fBPAPI_list_events()\fP returns an array of events and a count of the total number of events in an event set\&. This call assumes an initialized PAPI library and a successfully created event set\&.

\fIEventSet\fP An integer handle for a PAPI event set as created by \fBPAPI_create_eventset\fP 
.br
\fI*Events\fP A pointer to a preallocated array of codes for events, such as PAPI_INT_INS\&. No more than *number codes will be stored into the array\&. 
.br
\fI*number\fP On input, the size of the Events array, or maximum number of event codes to be returned\&. A value of 0 can be used to probe an event set\&. On output, the number of events actually in the event set\&. This value may be greater than the actually stored number of event codes\&.
