ta-lib port for ruby using swig

[BENI]

I was trying to SWIG onto the ta-lib .

the ta-lib is a collection of c functions for financial data analysis.

http://ta-lib.org/d_api/d_api.html.


I was trying with one function.

the header

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


the c call:
Lets say you wish to calculate a 30 day moving average using closing
prices. The function call could look as follow:

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 was wondering how the typemap for the arguments in swig will look
like.

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


Any lead will be very helpful.

btw. i have all the docs rltd to swig and the pickaxe as well.
