I'm trying to connect perl and C together. I know how to call perl from C code, by creating a new PerlInterpreter.

I've also played with calling C from perl code, by creating xsubs.

But what I really want to do is call perl from C, and then from that perl, call functions back in the original C, but more importantly I need to make this a library that I can link in with a C program.

In other words, I need to be able to do something like this: 

C CODE:

int some_Cvar;  // Global to C
int main (void) {
  call_perl("some_perl_func");
  printf("C: some_Cvar = %d\n",some_Cvar);
}

int set_some_Cvar (int val) {
  some_Cvar = val;
}

-------------------------

PERL CODE:

sub some_perl_func {
  print "In perl - setting some_Cvar\n";
  set_some_Cvar(42);
}

And most importantly I need to be able to do it as a library, since I'm linking it with a program that I don't have the source for... (don't ask :)
