Hi Everyone, I'm interested in whether it is possible to get the size of a variable a pointer is pointing at. I have a function that accepts a char * pointer. This can either be stack or heap memory but more typically stack where I see it. It would help me tremendously if I could figure out the size of the variable at the other end of the pointer. I can't think of a way to do this unfortunately. strlen won't work as the variable is null when passed in sizeof(*ptr) returns 1, even though the memory is larger sizeof(ptr) returns 4 (on my 32 bit machine) of course Can anyone think of how to do this, or am I out of luck? Thank you in advance, Andrew
