+ * Name: posix_spawn_file_actions_destroy
+ *
+ * Description:
+ *   The posix_spawn_file_actions_destroy() function destroys the object
+ *   referenced by file_actions which was previously intialized by
+ *   posix_spawn_file_actions_init(), returning any resources obtained at the
+ *   time of initialization to the system for subsequent reuse.  A
+ *   posix_spawn_file_actions_t may be reinitialized after having been
+ *   destroyed, but must not be reused after destruction, unless it has been
+ *   reinitialized.
+ *
+ * Input Parameters:
+ *   file_actions - The posix_spawn_file_actions_t to be destroyed.
+ *
+ * Returned Value:
+ *   On success, these functions return 0; on failure they return an error
+ *   number from <errno.h>.
