+//!
+//! <b>Postconditions</b>: get_default_resource() == r.
+//!
+//! <b>Returns</b>: The previous value of the default memory resource pointer.
+//!
+//! <b>Remarks</b>: Calling the set_default_resource and get_default_resource functions shall
+//!   not incur a data race. A call to the set_default_resource function shall synchronize
+//!   with subsequent calls to the set_default_resource and get_default_resource functions.
