hi, i am new to valgrind and was planning to use valgrind function wrapping for testing my system (particularly to hit the error and rare cases in the system which are hard to occur). here are a couple of questions: #1. all examples i saw in the documentation are with C functions. There is a mention of C++ doing wrapping based on wildcard matches in soname and function name. if i understand this correctly, i cannot specify the wrapper using class::member syntax -- it should be flattened names, correct? is there any experience/examples of this?
#2. if yes, what are the limitations (e.g. does the member function need to be defined outside the class definition? this is just an example - pls add any other limitations that you are aware of) #3. how do i specify wrappers to functions with object reference as parameters? what about default parameters - how to specify in the wrappers? variable number of arguments ...? feel free to add any other such limitations. #4. will function wrapping work across dynamic binding/polymorphism? do i need to do anything special for it to work correctly? (as long as i specify as the wrapper for the appropriate class's function i hope it should work in that valgrind would act once the dynamic binding is resolved, rite?) #5. my system's code uses the STL for C++. is there any caveats in this regard? i would imagine not but just wanted to be sure before i started. #6. i noticed one of the caveats was the limited number of options available for calling the original function. is there a way around it (since the system i have to test doesnt naturally fall in that restriction)? what i want to do is to use the wrapper function under certain circumstances (controlled by user e.g. to inject faults) and use the original function otherwise. with that in view i was planning to call the original function from the wrapper function and was getting cramped by this caveat. what suggestions do you have for getting around this problem? #7. is there any inbuilt/efficient valgrind mechanism to know the call stack at a given location? if so where can i get more information on that? look forward to your responses thanx -venky ------------------------------------------------------------------------------ Are you an open source citizen?
