Inline::C and arrays

[Scott Prahl]

Hi,

I am having trouble figuring out how to use Inline to interface with
a library that handles arrays.  To be specific, consider

void trig(int n, double * angles, double ** cosines, double ** sines)
{
        int i;
        *sines   = (double *) malloc(n*sizeof(double));
        *cosines = (double *) malloc(n*sizeof(double));

        for (i=0; i<n; i++) {
                (*cosines)[i] = cos(angles[i]);
                (*sines)[i]   = sin(angles[i]);
        }
}

What sort of Inline wrapper should be used to allow

($cosine, $sine) = trig_wrap(n, \@angles);

where $cosine and $sine are references to perl arrays?

Thanks,
Scott
