complex wire buffer format

What is the format for a complex wire buffer?  I am assuming it would packed real then complex.  Is this correct?

So an example for accessing the complex data would be:  

awe_modaxisSBInstance *S = (awe_modaxisSBInstance *)pInstance;
WireInstance **pWires = ClassModule_GetWires(S);

cplx *src = (cplx *)pWires[0];
cplx *sbL = src+0;
cplx *sbR = src+1;
cplx *dst = (cplx *)pWires[1];
cplx *subBandVcaL = dst+0;
cplx *subBandVcaR = dst+1;
TaxisSB *A = (TaxisSB *)S->aStruct;

axisSB
(
        A, 
        sbL, 
        sbR, 
        subBandVcaL, 
        subBandVcaR
);

cplx is defined as:

typedef struct {
    float r;
    float i;
}cplx;
