premchai21 has asked for the wisdom of the Perl Monks concerning the following question:

I am attempting to write a C program that uses libperl and its associated structures (xV in particular). I would like to access Perl's built-in functions (i.e. those listed in perlfunc), but I haven't been able to find any documentation on doing so. I've read perlapi and perlembed, among other docs, but haven't found much of help, though it's likely I've missed something. It seems as if I might have to manipulate the/an opcode tree (just based on output from B::C), but that seems frightening, mostly because I really don't know how, and can't find a good reference.

Are there any suggestions from the kind monks?
