| -- OBJECTIVE: |
| -- Check that the specifications of the package Interfaces.C.Pointers |
| -- are available for use. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test verifies that the types and subprograms specified for the |
| -- interface are present |
| -- |
| -- APPLICABILITY CRITERIA: |
| -- If an implementation provides package Interfaces.C.Pointers, this |
| -- test must compile, execute, and report "PASSED". |
| -- |
| -- |
| -- CHANGE HISTORY: |
| -- 06 Dec 94 SAIC ACVC 2.0 |
| -- 28 Feb 96 SAIC Added applicability criteria. |
