What is even the point of the JNI if the JIT compiler exists?

Is it possible to handle a SEGFAULT orginating in native code?
by Andrew Forbes in Programming Languages

I have a Java 1.6 application that accesses a third party native module, through a JNI class provided as the interface. Recently we noticed that a SEGFAULT is occurring in the native module, and is causing our application to crash. Is it possible to catch and handle this event, at least to log


loading managed resources from c# and passing it to Native CPP code as a stream handle
by kraszie in Programming Languages

I have a file that I have embedded as a resource in a managed C# assembly. I would like to pass the pointer to that resource and its size to some native code so it can extract it for me if needed. Are there C# api's that give me the intptr of that embedded resource?

Sometimes, that native method throws an exception which I catch in my managed code. However, when i print the stacktrace from my caught exception, I see only managed code (the last fram


Problems debugging C++ Android native code in Eclipse (Native-Audio example)
by licensing in Programming Languages
I'm trying to understand the inner workings of the Native-Audio example that comes with the NDK. To do this I'd like to step through the C code in a debug mode, but I've been having several issues attempting to do this. Here are the steps I am taking:1) In Eclipse, File -> New -> Android Project fro
Why would native code called from .net give different result from calling it from a native program?
by flakekun in Programming Languages

We've got a native library which we use to perform security related tasks for us. We've written an interop library so that we can use it from .NET.


We've got two test applications, the first application is written in C++ (unmanaged) and the second is written in C#. They generate the

Did someone test it?? Is this serious?
Or is there some free or at least more cheap alternative?
