Re: [Lcms-user] multi threaded fork

[Marti <mar...@li...>]

Thanks Vicent,

I  am already in contact with Artifex, they told me about their fork.

Please note lcms already is multi-threading capable, and some critical
functions like cmsDoTransform are re-entrant.   By default, it uses pthreads
on everything but windows, that uses critical sections instead. 

Artifex have added a way to pass parameters to each function to identify the
thread,  but unfortunately this breaks all compatibility with prior APIs, so
I had to reject the changes on upstream because compatibility sake.  The
"normal" lcms is based on contexts. It allows you to change via plug-in's
the locking strategy and the memory allocation. 

Regards
Marti
