Calling a C program from Perl can be done with the XS mechanism. XS stands for

However, you may need to learn something about Perl internals.
I know some basics about XS and I've written some small modules to get
access to C functions that aren't available in plain Perl.
I've also successfully written my own small example program that calls a
perl script in an embedded interpreter.
What I'm missing is the glue between both worlds.
Is it possible to embed a perl interpreter in a C program, which itself
defines a function "Foobar" which is declared in "foobar.h". Now I use
the same "foobar.h" in a XS perl module to use this C interface. Is it
possible to make my "module" interact with the function defined in the C
program that embeds the interpreter?
The idea is to somehow embed a perl interpreter into some software which
only allows C to be used to write plugins. Those plugins are small ".so"
files that have to use some header files which define the API. I somehow
want to export the plugin API "into the Perl world" to make it possible
to write plugins in Perl.
