Sharing scalars with cloned interpreter
|
|
Hello,
I havent found any relevant posts on this topic, so hoping the experts can rescue me.
I'm extending Perl and also embedding a cloned interpreter. I use the cloned interpreter to invoke Perl sub's as callbacks. The callback part is working fine. However, a variable changed in the callback subroutine is NOT becoming available in the rest of the perl script.
I tried to "use threads:shared" and ":shared" the variable in question, but perl exits, complaining that another completely unrelated scalar is "Invalid value for shared scalar at".
How can I "share" variable updates between the main perl script and the callbacks invokved thru the cloned interpreter?
I'm using v5.8.8 perl. perl_clone() is using CLONEf_COPY_STACKS | CLONEf_KEEP_PTR_TABLE. The perl sub is sv_dup() with the same flags in CLONE_PARAMS before call_sv().
Please see this post that describes my current code.
