in thread XS from XS?

If I understand that right--and I'm not certain I am--you are importing the Perl callable functions in one XS module, into the namespace of another XS module?

He's saving the address of functions callable from C in the current Perl package.

    The PL_modglobal hash isn't quite the same thing as the general symbol table. From perlapi:
    PL_modglobal is a general purpose, interpreter global HV for use by extensions that need to keep information on a per-interpreter basis. In a pinch, it can also be used as a symbol table for extensions to share data among each other. It is a good idea to use keys prefixed by the package name of the extension that owns the data.

    However, storing the addresses in scalar package globals accessed from C via get_sv() would be another approach and might actually be better.

      Thankyou. That clarifies things a lot for me.
