Hello everyone, Now that everything is in SVN, I would like to start working on the code again.
There is one important aspect which still needs a solution: Exception handling Celix follows the OSGi spec (Java), but since C doesn't have exceptions like Java, a solution is needed to be able to report errors/exceptions. I've been looking on the web, and found 2 possible solutions. 1) Using a library that uses setjmp/longjmp: Examples are: - http://libexcept.sourceforge.net/ - http://www.nicemice.net/cexcept/ - http://code.google.com/p/exceptions4c/ 2) Use the return value of functions: - For example by simply returning a int value indicating the error - Use a library which supplies try/catch macros: http://code.google.com/p/libex/ The first solution makes it possible to have an API very similar to the OSGi spec, but I am not sure how setjmp and longjmp interact with threads and real time behavior. The second solution is the most simple, and with the help of a library it is still possible to have clear code with try/catch constructs. Does anyone have any experience with these kind of libraries? For now I tend to lean towards using a simple solution, either simply returning the error code, or using something like libex (which is lgpl, which might be a problem..). -- Kind regards, Alexander Broekhuis
