restrict

 

The latest version of this topic can be found at restrict.

Microsoft Specific**

Applied to a function declaration or definition that returns a pointer type and tells the compiler that the function returns an object that will not be aliased with any other pointers.

Syntax

__declspec(restrict) return_type f();  

Remarks

The compiler will propagate __declspec(restrict). For example, the CRT malloc function is decorated with __declspec(restrict) and therefore, pointers initialized to memory locations with malloc are also implied to not be aliased.

The compiler does not check that the pointer is actually not aliased. It is the developer's responsibility to ensure the program does not alias a pointer marked with the restrict __declspec modifier.

For similar semantics on variables, see __restrict.

Example

See noalias for an example using restrict.
