Just don't put anything in the buffer if the user didn't supply enough space. As long as you get the return value right, they know the string is bad (or they don't care if the string is bad)
It might be that I'm out of context here, but printf() functionality in the kernel (vsprintf() if being precise) and its users consider that it should fill buffer up to the end of whatever space is available. -- With Best Regards, Andy Shevchenko
