// The restrict declspec is used on functions that return unaliased pointers. This keyword is used for the C-Runtime Library implementation of malloc since it will never return a pointer value that is already in use in the current program (unless you are doing something illegal, such as using memory after it has been freed).

// The noalias declspec is also applied only to functions, and indicates that the function is a semi-pure function. A semi-pure function is one that references or modifies only locals, arguments, and first-level indirections of arguments. This declspec is a promise to the compiler, and if the function references globals or second-level indirections of pointer arguments then the compiler may generate code that breaks the application.
