Perl extension and Multiple Threads

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

Can someone please tell me if there's anything special I have to do in building a Perl extension if it's going to be called by a multi-threaded Perl script? Thanks!!

Not all modules have been updated to the current threading API, so you should check what you're building to see if it's thread safe. Look for the `pTHX_` macro at the start of all the subroutine declarations. After Compline, Zaxo	[reply]

I had some problems with file interlockings previously, so you might want to take care of that.	[reply]
