I hope someone can provide some guidance on how I can solve a certain
problem.
I have a library that taps into the ghc c rts: specifically when the rts
is single threaded I am pumping events in via: stg_pending_events, when
the threaded rts is used I use sendIOManagerEvent.
These are RTS internal APIs, and could change under your feet. What is
it you're trying to do exactly?
i.e. I have two versions of the library with the same api. The problem
with this is that either library is only good for one context: either
threaded rts or not, and the user needs to select the appropriate
library to use depending on the use context.
What I want to be able to do is to have ghc automatically select the
compiled library version to link in depending on the which rts option is
selected: "-thread" or not
Library code is generally supposed to be independent of -threaded;
sometimes we do this by checking at runtime using rtsSupportsBoundThreads().
Cheers,
Simon
