- * Type of a signal handling function.
- *
- * Language spec sez signal handlers take exactly one arg, even though we
- * actually supply three.  Ugh!
- *
- * We don't try to hide the difference by leaving out the args because
- * that would cause warnings about conformant programs.  Nonconformant
- * programs can avoid the warnings by casting to (__sighandler_t *) or
- * sig_t before calling signal() or assigning to sa_handler or sv_handler.
- *
- * The kernel should reverse the cast before calling the function.  It
- * has no way to do this, but on most machines 1-arg and 3-arg functions
- * have the same calling protocol so there is no problem in practice.
- * A bit in sa_flags could be used to specify the number of args.
