84 * This module specifies some #defines for privates types in the
85 * interface. In this way we warn the FRSH user never to access the internal
86 * members of the types directly allowing us to change their internal
87 * definitions to suit our needs.
89 * Note that in Ada the FRSH user would never be allowed to access the
90 * members directly, however in C the compiler does not prevent this.
91 * But this is the best we can do in this language.
