How can I use mlock() for NSString and NSTextField?
As argument to mlock is address of memory area and length.
I have address of memory area but I do not have the length (as these
are objects).
class_getInstanceSize() will tell you how big an instance of NSString
or NSTextField is. But the data you're trying to protect won't
necessarily be inside that range. For example, NSString often uses
another allocation internally to hold the string data, and you have no
way to know where that is.
