+ * Test Name: getpid01
+ *
+ * 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.
+ *
+ * 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>
+ * getpid01 [-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.
