A question about programming using dynamically linked function

[jiaguo]

Hi

I am writing dynamically linked functions. In my function, I
need to copy the data from a complex matrix (in octave_value
type) to a double buffer. I was wondering if there is a way to
find a pointer to the real data in the complex matrix (in
octave_value type), so that I can use memcpy to copy it to my
own buffer. The similar function can be found in MATLAB which
is mxGetPr. Does Octave have similar functions like mxGetPr?

Thanks a lot!
