Re^3: Use perl type without perl

In a single-threaded perl, there is only one copy of stuff like current working directory, environment etc.

In a multi-threaded perl, each thread needs its own copy of that information.

So, for the single-threaded perl, the PERL_CONTEXT can be known at compile time and linked statically into code. A single static pointer to a struct that contains all the per-thread information is all that is required, because there is only one thread.

In a multi-threaded perl, each function that needs access to the "current PERL_CONTEXT" need to be able to find the appropriate context for the thread it is running in; hence it needs the my_perl variable which tells it which context that is.

Just because in single threaded perl there is no my_perl doesn't mean you can use the types without initializing/having a perl interp set up. SV *s aren't straight malloced from the C lib but come out of a pool the interp maintains.	[reply]

No. Either I reply to your post or to Re: Use perl type without perl. Someone who didn't read the manual will think they can use Perl C data structures without a "useless" Perl around instead of GObject.	[reply]
