I'm currently writing the memory management section of my operating system, but I've got a problem with my malloc() function. Specifically, the compiler doesn't like my use of the binary AND operator here:


if ((currentMemory & (1<<loops)) == (1<<loops))

To the best of my knowledge, this is a correct statement. Even when I replace the whole (1<<loops) thing with a constant, it still spits out the same error. Can anybody tell me what is wrong with this statement?

Is currentMemory a pointer? You can only use the binary & operator on integer types.

That was it! Thanks a lot, that had me puzzled for a while.
