[Billy Patton]

I have a c library I have connected to perl via XS.
Originally I wrote the c to write c programs.  I've since
quit writing any c programs and write entirely in perl.

The original c was written with perl in mind.  Since though
I have rebuilt many of the c functions to better align
with perl:

Here is some of my XS code:
void
LayerExtent(cp,ln)
  Laff::Cell  cp
  char*       ln
PPCODE:
{
  int llx,lly,urx,ury;
  if (! LayerExtent(cp,ln,&llx,&lly,&urx,&ury)) XSRETURN_NO;
  XPUSHs(sv_2mortal(newSViv(llx)));
  XPUSHs(sv_2mortal(newSViv(lly)));
  XPUSHs(sv_2mortal(newSViv(urx)));
  XPUSHs(sv_2mortal(newSViv(ury)));
  XSRETURN(4);
}


The names are the same but the C version needs to return
4 values.
Since I'm currently in the process of rebuilding my C and my
XS to align, should I move all the XSPUSH into my c code?
Other than reducing the amount of xs code. 
What would be the +'s and -'s of doing this?

So that I could simply do:

void
LayerExtent(cp,ln)
  Laff::Cell  cp
  char*       ln

This would be VERY low maintenance XS :)
