Hello, I'm trying to use the limited connections api defined in Rinternals.h. I have code that looks like this (inspired from do_serializeToConn) : SEXP serialize_to_connection( SEXP xp, SEXP connection ){ Rconnection con ; struct R_outpstream_st out; R_pstream_format_t type = R_pstream_binary_format ; SEXP (*hook)(SEXP, SEXP) = NULL ; con = getConnection(Rf_asInteger(connection));

Hi, We're planning to use Protocol Buffers (Google's data interchange format: http://code.google.com/apis/protocolbuffers/ ) in a future version of Compiz and libcompizconfig to speed up metadata parsing, which currently makes up more than 75% of the start-up time for Compiz according to Valgrind. Preliminary work in this direction has shown promising results. We'll be adding libprotobuf as an optional depende...

...to file can be found in the source. Todo: Very possible though needs some reading on my part: it is possible to extend this to serialize functions, expressions, environments and several other objects. However that is some time in the future.

I looked into this further. ld64 has a macho_nlist abstraction over the various underlying nlist structures [1]. On x86-64, the P::getP referenced in n_value will resolve to [2], which in turn goes to [3], which calls OSReadLittleInt64. On a little endian machine, OSReadLittleEndian just calls _OSReadInt64 [4], which in turn does a pointer arithmetic and cast and then dereferences the pointer [5].

Hey Bjorn, Were you able to figure this out or is it still broken for you? Our scenario is a little bit different, but I have a theory as to what may be going wrong. What linker are you using when you compile your project with clang-cl? I am wondering whether the version of the linker and/or the libraries that you are using is too old in comparison to the one used for the clang compilation.
