MISRA_BUDGET_ALLOCATOR_MAGIC

MISRA_BUDGET_ALLOCATOR_MAGIC

Description

Per-type magic for BudgetAllocator. Stamped into Allocator.base.__magic by BudgetAllocatorInit*. The budget implementation functions validate this exact value so other allocator instances reinterpreted as a BudgetAllocator * are rejected at runtime as type-confusion.
