Hello everyone, I just got started with Julia, and I wanted to try to wrap a C/C++ library to Julia to check whether it would work out for my purposes.
I tried out many ways of passing arrays and other objects from C back to Julia. So far it seems that it takes a lot of extra code if I want to return, for example, a simple double-array or an array of types (eg structs). Then I thought that I could call the Julia API from the ccalled binary, to allocate an array and return it to julia, then use unsafe_pointer_to_objref() and get a neat Julia object directly. You can see a very simple example here https://gist.github.com/anonymous/8888647 This would simplify _significantly_ a lot of code from the C side, at least with what I am working right now. Now, my question is: is it safe to call functions such as jl_alloc_array_1d() from the C binary? would this be a problem in some situations? I understand that it may mess memory up if those functions are called outside the main thread, but I would certainly not do that. Thanks in advance, Carlos
