- * NAME
- * getsid01.c
- *
- * DESCRIPTION
- * getsid01 - call getsid() and make sure it succeeds
- *
- * ALGORITHM
- * loop if that option was specified
- * issue the system call
- * check the return value
- * if return value == -1
- * issue a FAIL message, break remaining tests and cleanup
- * if we are doing functional testing
- * save the return value from the getsid() call - the session ID
- * fork a child and get the child's session ID
- * if the child's session ID == the parent's session ID
- * issue a PASS message
- * else
- * issue a FAIL message
- * else issue a PASS message
- * call cleanup
- *
- * USAGE: <for command-line>
- * getsid01 [-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

+/*\
+ * [Description]
*
- * RESTRICTIONS
- * none
+ * Verify that session IDs returned by getsid() (with argument pid=0)
+ * are same in parent and child process.
