// NOTE:
//   This should take a type of size_t.  But size_t has an unknown underlying
//   type.  In the nuttx sys/types.h header file, size_t is typed as uint32_t
//   (which is determined by architecture-specific logic).  But the C++
//   compiler may believe that size_t is of a different type resulting in
//   compilation errors in the operator.  Using the underlying integer type
//   instead of size_t seems to resolve the compilation issues. Need to
//   REVISIT this.
