How can I print out the Memory Adress of an variable?

Question

I'd like to print what's behind an &myVariable. I tried NSLog(&myIntVar); but it won't work.

Answer 1

The argument to NSLog needs to be an NSString, so you want

NSLog(@"%p", &myIntVar);

Answer 2

Try:

NSLog(@"%p", &myIntVar);

or

NSLog(@"%lx", (long)&myIntVar);

The first version uses the pointer-specific print format, which assumes that the passed parameter is a pointer, but internally treats it as a long.

The second version takes the address, then casts it to a long integer. This is necessary for portability on 64-bit platforms, because without the "l" format qualifier it would assume that the supplied value is an integer, typically only 32-bits long.
