QUOTE(cse-icons @ Jan 25 2005, 07:16 AM) hi everyone, here is an exercise for u... I found it quite interesting... hope u like it too.... The question is : How do you call a function, given its name as a string? Try it out and post the solution/example.... or post ur approach to the sol... a hint: the solution is not very difficult... I will post the solution next week.... cya, keep trying... All the best. Cheers.  You may try something like function pointer. I have an article about this: http://www.trap17.com/forums/trap17-file-no-833.html modify it to fit your use.
Oh, I have interest in this question.
trap17-file-no-833.html is somewhat too simple and means nothing. Vxworks do this way very well, but I still don't know how it works. Waiting for your solution.
I know with dynamically linked libraries you can get a function reference by passing a string that contains the function name. So you just compile the functions as a DLL it will work.
but params,
how to give the correct params? like: func("asdf",1) QUOTE(s243a @ Jan 26 2005, 05:07 AM) I know with dynamically linked libraries you can get a function reference by passing a string that contains the function name. So you just compile the functions as a DLL it will work.
