number of arguments function for 4.1bsd VAX cc(1) -- TYPO FIX

[Gordon V. Cormack]

This sample program illlustrates a much simpler way to find the
number of arguments to a function on the VAX, and to access an
indeterminate number of arguments.  

    #include <stdio.h>

    main()
    {
	pr_args(1);
	pr_args(1, 2, 3);
	pr_args(1, 2, 3, 4);
    }
    pr_args(args)
	int args;
    {
	int nargs, *argp, i;
	argp = &args;
	nargs = argp[-1];
	printf("Called with %d args: ", nargs);
	for(i=0; i<nargs; i++) printf( "%d ", argp[i] );
	putchar('\n');
    }
