In the C programming language, restrict is a keyword, introduced by the C99 standard, [1] that can be used in pointer declarations. By adding this type qualifier , a programmer hints to the compiler that for the lifetime of the pointer, no other pointer will be used to access the object to which it points.
Use a minimum of two runtime assertions per function. Restrict the scope of data to the smallest possible. Check the return value of all non-void functions, or cast to void to indicate the return value is useless. Use the preprocessor sparingly. Limit pointer use to a single dereference, and do not use function pointers.

C supports the use of pointers, a type of reference that records the address or location of an object or function in memory. Pointers can be dereferenced to access data stored at the address pointed to, or to invoke a pointed-to function. Pointers can be manipulated using assignment or pointer arithmetic. The run-time representation of a ...
The first two of these, const and volatile, are also present in C++, and are the only type qualifiers in C++. Thus in C++ the term "cv-qualified type" (for const and volatile) is often used for "qualified type", while the terms "c-qualified type" and "v-qualified type" are used when only one of the qualifiers is relevant.

In this video, a German Shorthaired Pointer is definitely earning the title of “bird dog” with her ongoing obsession with a wild bird who tried to build her nest under the family’s deck.
In computer science, pointer analysis, or points-to analysis, is a static code analysis technique that establishes which pointers, or heap references, can point to which variables, or storage locations. It is often a component of more complex analyses such as escape analysis. A closely related technique is shape analysis.
