This document lists each possible API impact that could occur in transitioning source code to the new release of HP-UX. The impacts are sorted by HP-UX release number and by severity. For a description of the classifications of these impacts, see Overview of Impact Classifications.

To help you determine which of these impacts apply to your source code, the Linux STK contains file scanners (scansummary and scandetail) that can detect API transition impacts in your source files.

For more information, see Source code scanning tools.
