Accessing passed parameters in an oct file

[mpender]

I'm new to using mkoctfile to integrate C++ with Octave and I'm struggling to
figure out how to access the parameters passed in a call to the C program. 
I make a call from Octave like this:

reservememory (dimensionone, dimensiontwo);

and then in the file reservememory.cc I've tried to access the passed
parameters like:
int parm1, parm2;
parm1 = floor(args(0).floor());
parm2 = floor(args(1).floor());

Matrix tmp1 (parm1, parm2);
Matrix tmp2 (parm1, parm2);

set_global_value("P1", tmp1);
set_global_value("N1", tmp2);

I think the parameters are actually passed as doubles or arrays of doubles
and I can't find the right member function to just extract the values as
scalar integers. I want integers so I can use the numbers as array indices,
but even working with doubles would be a significant step forward at this
point.  

The array indices are then used to reserve the memory in the C code instead
of within Octave.  I understand there is some sort of Octave local memory
reserve function available for this, but this code is a bridge I'm using to
move from a completely Octave implementation to an NVIDIA-CUDA
implementation.

Thanks, Mike
