Subject: SWIG typemap for ta-lib

I was trying to swig a function in ta-lib (TA-Lib provides common
functions for the technical analysis of financial market data)
http://ta-lib.org/index.html

the c functuon api

TA_RetCode TA_MA( int          startIdx,
                  int          endIdx,
                  const double inReal[],
                  int          optInTimePeriod,
                  int          optInMAType,
                  int         *outBegIdx,
                  int         *outNbElement,
                  double       outReal[],
                )

===========

the c call
==========

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] );

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



the query''''''

what should be the typemap

for  argument

                 1>const double inReal[],
                  2>int         *outBegIdx,
                  3>int         *outNbElement,
                  4>double       outReal[],



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