Whitesmiths Ltd. had (still has but are now called WSL extensions to ANSI C),
several library routines dealing with multiple copy operations. For example:

	/* I do not recall the return value, but I think it is */
	char *cpystr(destination, _1st_source [, _2nd_source, ...], NULL)
		char *destination, *_1st_source, *_2nd_source, ...;

	/* last arg passed has to be `NULL' */

so that you can say:

	char buf[BUFSIZ];
	cpystr(&buf[0], "This ", "is ", "a test", NULL);

I think this will do what, the original code that was posted, was trying to.
(Yes/No)?
