Yeah, the program will take in a declaration of a (basic) struct, with doubles, floats, and integer members. It'll generate an LLVM program that'll read that sort of struct from a shared memory segment. >> Also, is everything under LLVM.Core.* private (not LLVM.Core, but >> LLVM.Core.Util,etc)?

I'd like to get the runtime arguments of a function. In my case, main()'s command-line arguments to get the shared-memory ID. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
