Here's an example of the way that I've done it in the past. Hope this helps.

Code:
#!/usr/bin/expect -f
#
# example of executing a command with expect
# and retrieving an exit\return code
#

# set credentials
set u ""
set p ""

# set hostname
set h ""

# set command to run
set cmd "CMD 2>/dev/null"

# capture the return code from the command
set retval "echo 'Return Code: '$?"

# spawn the ssh connection, run the command,
# and retrieve the return code
spawn ssh $u@$h "$cmd;$retval"
expect "?assword*"
send -- "$p\r"
send -- "\r"
expect -re {Return Code: (\d+)}
set retval $expect_out(1,string)
expect eof

# process the return code
if {$retval != 0} {
    puts stderr "Fail"
} else {
    puts stderr "Pass"
}

PAPI_add_events(3)						       PAPI							PAPI_add_events(3)

NAME

       PAPI_add_events -

       add multiple PAPI presets or native hardware events to an event set

SYNOPSIS

Detailed Description
       @par C Interface:
       int PAPI_add_events( int  EventSet, int * EventCodes, int  number );

       PAPI_add_event adds one event to a PAPI Event Set. PAPI_add_events does
       the same, but for an array of events. @n
       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 avail test case
       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 current platform, run native_avail
       test case in the PAPI distribution. For the encoding of native events,
       see PAPI_event_name_to_code to learn how to generate native code for the
       supported native event on the underlying architecture.

       @param EventSet
	   An integer handle for a PAPI Event Set as created by PAPI_create_eventset.
       @param *EventCode
	   An array of defined events.
       @param number
	   An integer indicating the number of events in the array *EventCode.
	   It should be noted that PAPI_add_events can partially succeed,
	   exactly like PAPI_remove_events.

       @retval Positive-Integer
	   The number of consecutive elements that succeeded before the error.
       @retval PAPI_EINVAL
	   One or more of the arguments is invalid.
       @retval PAPI_ENOMEM
	   Insufficient memory to complete the operation.
       @retval PAPI_ENOEVST
	   The event set specified does not exist.
       @retval PAPI_EISRUN
	   The event set is currently counting events.
       @retval PAPI_ECNFLCT
	   The underlying counter hardware can not count this event and other events
	   in the event set simultaneously.
       @retval PAPI_ENOEVNT
	   The PAPI preset is not available on the underlying hardware.
       @retval PAPI_EBUG
	   Internal error, please send mail to the developers.

       @par Examples:

       *   int EventSet = PAPI_NULL;
       *   unsigned int native = 0x0;
       *   if ( PAPI_create_eventset( &EventSet ) != PAPI_OK )
       *   handle_error( 1 );
       *   // Add Total Instructions Executed to our EventSet
       *   if ( PAPI_add_event( EventSet, PAPI_TOT_INS ) != PAPI_OK )
       *   handle_error( 1 );
       *   // Add native event PM_CYC to EventSet
       *   if ( PAPI_event_name_to_code( "PM_CYC", &native ) != PAPI_OK )
       *   handle_error( 1 );
       *   if ( PAPI_add_event( EventSet, native ) != PAPI_OK )
       *   handle_error( 1 );
       *
