+ *
+ * Purpose:     Re-parse the file locking environment variable.
+ *
+ *              Since getenv(3) is fairly expensive, we only parse it once,
+ *              when the library opens. This test function is used to
+ *              re-parse the environment variable after we've changed it
+ *              with setnev(3).
+ *
+ * Return:      SUCCEED/FAIL

+ * Programmer:	Dana Robinson
