+ * process cleared the previously specified alarm request or not.
+ * 2) By the value returned by parent's alarm(0), check whether parent
+ * process cleared the previously specified alarm request or not.

- * AUTHOR : Richard Logan
- *
- * CO-PILOT : Dennis Arason
- *
- * DATE STARTED : 08/96
- *
- *
- * TEST CASES
- *
- * 1.) alarm(100), fork, child's alarm(0) shall return 0;
- * 2.) alarm(100), fork, parent's alarm(0) shall return non-zero.
- *
- * INPUT SPECIFICATIONS
- * The standard options for system call tests are accepted.
- * (See the parse_opts(3) man page).
- *
- *
- * SPECIAL PROCEDURAL REQUIREMENTS
- * None
- *
- *
- * DETAILED DESCRIPTION
- * This is a Phase I test for the alarm(2) system call. It is intended
- * to provide a limited exposure of the system call, for now. It
- * should/will be extended when full functional tests are written for
- * alarm(2).
- *
- * Setup:
- * Setup signal handling.
- * Pause for SIGUSR1 if option specified.
- *
- * Test:
- * Loop if the proper options are given.
- * Execute system call
- * Check return code, if system call failed (return=-1)
- * Log the errno and Issue a FAIL message.
- * Otherwise, Issue a PASS message.
- *
- * Cleanup:
- * Print errno log and/or timing stats if options given
- *
