class SetPointerPlugin : public mu::tiny::test::Plugin

Plugin that restores pointer variables to their original values.

Up to max_set pointers may be registered per test. The plugin records the address of each pointer variable before it is overwritten; on post_test_action() it writes the saved address back.

• a – Reference to the pointer variable to overwrite.
