1.100 + * Type of a signal handling function.
1.101 + *
1.102 + * Language spec sez signal handlers take exactly one arg, even though we
1.103 + * actually supply three. Ugh!
1.104 + *
1.105 + * We don't try to hide the difference by leaving out the args because
1.106 + * that would cause warnings about conformant programs. Nonconformant
1.107 + * programs can avoid the warnings by casting to (__sighandler_t *) or
1.108 + * sig_t before calling signal() or assigning to sa_handler or sv_handler.
1.109 + *
1.110 + * The kernel should reverse the cast before calling the function. It
1.111 + * has no way to do this, but on most machines 1-arg and 3-arg functions
1.112 + * have the same calling protocol so there is no problem in practice.
1.113 + * A bit in sa_flags could be used to specify the number of args.
