Try this:

struct MyClass_t {
  @defs(MyClass)
} *myClassPtr;

@implementation MyClass

- (id)init
{
  self = [super init];

  if(self) {
    myClassPtr = (struct MyClass_t *)self;
    ...
    ...
  }
  return self;
}

@end

Now you can use "myClassPtr" from a function, for example:

void c_function()
{
  NSData *data = myClassPtr->data;
}
