Subject: ta-lib porting with swig

I have a function in c from ta-lib (TA-Lib provides common functions
for the technical analysis of financial market data)
http://ta-lib.org/

 function header

=======
TA_RetCode TA_MA( int          startIdx,
                  int          endIdx,
                  const double inReal[],
                  int          optInTimePeriod,
                  int          optInMAType,
                  int         *outBegIdx,
                  int         *outNbElement,
                  double       outReal[],
                )
===========
In c it is called as

==========
TA_Real    closePrice[400];
TA_Real    out[400];
TA_Integer outBeg;
TA_Integer outNbElement;

/* ... initialize your closing price here... */

retCode = TA_MA( 0, 399,
&closePrice[0],
30,TA_MAType_SMA,
&outBeg, &outNbElement, &out[0] );

/* The output is displayed here */
for( i=0; i < outNbElement; i++ )
   printf( "Day %d = %f\n", outBeg+i, out[i] );
================================

i was wondering how will the typemap in SWIG  look like for arguments

const double inReal[]
int         *outBegIdx
int         *outNbElement,
  double       outReal[],

=============

can any one help me out by giving some lead?
