High Quality Content by WIKIPEDIA articles! In computer programming, an opaque pointer is a special case of opaque data type, a datatype that is declared to be a pointer to a record or data structure of some unspecified type. Opaque pointers are present in several programming languages including Ada, C, C++ and Modula-2. If the language is strongly typed, programs and procedures that have no other information about an opaque pointer type T can still declare variables, arrays, and record fields of type T, assign values of that type, and compare those values for equality.

In computer programming, an opaque pointer is a special case of opaque data type, a datatype that is declared to be a pointer to a record or data structure of some unspecified type.
