In the C programming language, restrict is a type qualifier that can be applied to a pointer to hint to the compiler that for the lifetime of that pointer, no other pointer will be used to access the same pointed-to object. This limits the effects of pointer aliasing, which can allow the compiler to make optimizations (such as vectorization) that would not otherwise be possible.
