[PD] arguments not passed to an external

Since my laptop's processor is an Intel Core 2, it's a little edian one,
right? How can I make my code versatile so that it can compile on either
little or big endian machines? I'm reading Pd's source code ([phasor~]'s
code, for example) but it's beyond my understanding. I kind of understand
the beginning of d_osc.c where the code will try to determine the endianess
of the machine, but when it comes to sorting arguments out depending on the
endianess, I'm at loss.
Another important question I still have is, how do I determine whether
there is a signal coming in the object's inlets, so I know whether to use
the values passed via arguments, or the vectors passed from the dsp method.
I'm asking the same thing over and over again...I'll stop for now.
Thanks
