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)

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,
&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?
