- * Purpose: Call 'exit()' to terminate application
+ * Purpose: Call 'exit()' to terminate application. Be careful not to
+ * overflow the exit value range since UNIX supports a very
+ * small range such as 1 byte. Therefore, exit(256) may end
+ * up as exit(0).
* Inputs: status - status for exit() to return
* Returns: none
* Programmer: Quincey Koziol
