- * Test Name: getpid02
- *
- * Test Description:
- * Verify that getpid() system call gets the process ID of the of the
- * calling process.
- *
- * Expected Result:
- * getpid() should return pid of the process on success.
+/*\
+ * [DESCRIPTION]
*
- * Algorithm:
- * 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,
- * Verify the Functionality of system call
- * if successful,
- * Issue Functionality-Pass message.
- * Otherwise,
- * Issue Functionality-Fail message.
- * Cleanup:
- * Print errno log and/or timing stats if options given
- *
- * Usage: <for command-line>
- * getpid02 [-c n] [-f] [-i n] [-I x] [-P x] [-t]
- * where, -c n : Run n copies concurrently.
- * -f : Turn off functionality Testing.
- * -i n : Execute test n times.
- * -I x : Execute test for x seconds.
- * -P x : Pause for x seconds between iterations.
- * -t : Turn on syscall timing.
- *
- * HISTORY
- * 07/2001 Ported by Wayne Boyer
- *
- * RESTRICTIONS:
- * None.

+ * Check that getppid() in child returns the same pid as getpid() in parent.
