| * This sample test aims to check the following assertions: |
| * |
| * If SA_SIGINFO is set in sa_flags and Real Time Signals extension is supported, |
| * sa_sigaction is used as the signal handling function. |
| |
| * The steps are: |
| * -> test for RTS extension |
| * -> register a handler for SIGHUP with SA_SIGINFO, and a known function |
| * as sa_sigaction |
| * -> raise SIGHUP, and check the function has been called. |
| |
| * The test fails if the function is not called |
