Hello monks,

I had been trying to pass a complex structure as an argument for a C function. I am trying to do it in XSUB. But I am unable to do so. I have read a number of tutorials, perldocs, ebooks but I am unable to find the solution. I tried to go through the C code generated by xsubpp, so that I can make out a way to do it. But I was unable to understand few things mentioned below:

XSprePUSH (i guess, to generated space in stack like EXTEND(sp, n) macro

dVAR (defined as dNOOP)

dXSARGS (I read about it in perldoc, but I feel that we can easily code without using this. so what is the real purpose of this macro? )

dXSTARG

Is it possible to understand the C code generated and write our own C code without using xsubpp/*.xs, so that we can have a in-depth knowledge of the things happening 'under the hood'?
