// Name: new

// 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.
