use of (void) type in C

[utzoo!decvax!harpo!ihnp4!ihldt!ll1!otuxa!we13!rjk]

Not only is void used in casting, it can be used (and IS used in USG 5.0
& System V) as function type declarations.  An example of such would be
the declaration of a function which is called as the second argument to
signal:

	void catchit(){ ++delcnt; }

	main()
	{	.
		.
		signal(SIG_INT, catchit);
		.
