.SH NAME
PAPI_assign_eventset_component \- Assign a component index to an existing but empty EventSet\&.
.SH SYNOPSIS

.PP
.SH "Detailed Description"
.PP
.PP
\fBC Interface:\fP
.RS 4
#include <\fBpapi\&.h\fP>
.br
PAPI_assign_eventset_component( int EventSet, int cidx );
.RE
.PP
\fBParameters\fP
.RS 4
\fIEventSet\fP An integer identifier for an existing EventSet\&.
.br
\fIcidx\fP An integer identifier for a component\&. By convention, component 0 is always the cpu component\&.
.RE
.PP
\fBReturn values\fP
.RS 4
\fIPAPI_ENOCMP\fP The argument cidx is not a valid component\&.
.br
\fIPAPI_ENOEVST\fP The EventSet doesn't exist\&.
.br
\fIPAPI_ENOMEM\fP Insufficient memory to complete the operation\&.
.RE
.PP
\fBPAPI_assign_eventset_component\fP assigns a specific component index, as specified by cidx, to a new EventSet identified by EventSet, as obtained from \fBPAPI_create_eventset\fP\&. EventSets are ordinarily automatically bound to components when the first event is added\&. This routine is useful to explicitly bind an EventSet to a component before setting component related options\&.
.PP
\fBExamples:\fP
.RS 4
.PP
.nf
int EventSet = PAPI_NULL;
if ( PAPI_create_eventset( &EventSet ) != PAPI_OK )
handle_error( 1 );
// Bind our EventSet to the cpu component
if ( PAPI_assign_eventset_component( EventSet, 0 ) != PAPI_OK )
handle_error( 1 );
// Convert our EventSet to multiplexing
if ( PAPI_set_multiplex( EventSet ) != PAPI_OK )
handle_error( 1 );
