[julia-users] cfunction result garbage collected

I'm not yet a 100% sure what is happening in my application, but I'm embedding Julia and using cfunction() to generate C-callable functions that at a later time invoke the registered julia code. I use a fairly standard pattern I think, of passing a pointer to a julia object that is retain in C

It's not an issue with either package: when there are two things with the same name, you need to be explicit about which one you want to use, either by qualify how you refer to is or by explicitly importing one of the two things with that name. On Wed, Sep 28, 2016 at 7:44 AM, K leo

[julia-users] Re: cfunction result garbage collected

I can't help you at all, but I would like to ask if you pass the cfunction() result to the C side. I've been playing with embedding Julia and discovered I could call a cfunction() directly from C, although I'm not sure that's a good practice.

[julia-users] Re: cfunction result garbage collected

Yeah that's what I do. I think that's kind of the point of it, although I think most people use it perhaps as in-scope callbacks, whereas I persist the callbacks and invoke them later, so additionally I have to retain the wrapped closures to prevent them being collected. On Wednesday,

[julia-users] Re: help understanding different ways of wrapping functions

Thanks so much for the tips. The culprit is the keyword argument (xRat=0.). Declaring it made the wrapped code twice as fast, but still way slower than the inline code. But making it positional made the wrapped code just a little slower than the inline code - big improvement. On Wednesday,

On a separate note, norm([u; v]) for scalar u and v is going to be a lot slower than hypot(u, v) or sqrt(u*u + v*v) (although the latter does not check for overflow the way hypot does). Allocating little arrays and calling "vector" functions for everything, even small computations on a few

As the error says, they both export a function called rle, so it is not possible to know which one you're trying to call, if you don't qualify them. Qualifying means writing "package name dot" and then the function, as seen below module A export f f(x::Int64) = x end module B export f
