[julia-users] How to feval?

Hi, I need to convert this piece of Matlab code [ps, orig_path] = feval(str2func(test), out_path); where 'test' is the name of a function and 'out_path' it unique input argument. I have read and re-read the eval function and for once it's clear for me how it works (sorry, I find

[julia-users] fieldoffsets and the C macro offsetof

Hi, When we have a immutable that mimics a C struct, are the results of fieldoffsets() from the Julia side and offsetoff() at the C side supposed to give the same result? (Well, I already found one case were they don't)

Re: [julia-users] fieldoffsets and the C macro offsetof

you'll notice that it is size_t in C an Cint in Julia (converted with Clang). If I change the Julia type to Csize_t than the offsets are the same. Now I'm really going to sleep. sexta-feira, 11 de Setembro de 2015 às 04:07:53 UTC+1, J Luis escreveu: > > No, that's not the case. Pure C
