    dereference (third-person singular simple present dereferences, present participle dereferencing, simple past and past participle dereferenced)

    1. (programming) To access the value or object located in a memory location addressed by a pointer or another value interpreted as such; to access a value being referenced by something else.
      Attempting to dereference a null pointer often results in a crash.
