Locks-and-keys (computing)
text:
Locks-and-keys is a solution to dangling pointers in computer programming languages. The locks-and-keys approach represents pointers as ordered pairs where the key is an integer value. Heap-dynamic variables are represented as the storage for the variable plus a cell for an integer lock value. When a variable is allocated, a lock value is created and placed both into the variable's cell and into the pointer's key cell. Every access to the pointer compares these two values, and access is allowed
