 #ifndef SIGCHAIN_H

-/**
- * Code often wants to set a signal handler to clean up temporary files or
- * other work-in-progress when we die unexpectedly. For multiple pieces of
- * code to do this without conflicting, each piece of code must remember
- * the old value of the handler and restore it either when:
- *
- *   1. The work-in-progress is finished, and the handler is no longer
- *      necessary. The handler should revert to the original behavior
- *      (either another handler, SIG_DFL, or SIG_IGN).
- *
- *   2. The signal is received. We should then do our cleanup, then chain
- *      to the next handler (or die if it is SIG_DFL).
- *
- * Sigchain is a tiny library for keeping a stack of handlers. Your handler
- * and installation code should look something like:
- *
- * ------------------------------------------
- *   void clean_foo_on_signal(int sig)
- *   {
- * 	  clean_foo();
- * 	  sigchain_pop(sig);
- * 	  raise(sig);
- *   }
- *
- *   void other_func()
- *   {
- * 	  sigchain_push_common(clean_foo_on_signal);
- * 	  mess_up_foo();
- * 	  clean_foo();
- *   }
- * ------------------------------------------

-/**
- * Handlers are given the typedef of sigchain_fun. This is the same type
