However, I know of vfprintf() and I know how to use it. I mentioned these in my request. Here is another way to express my problem. I have a linked list of data; I want each element to be an argument to the error routine; I want to call the error routine only one time for the entire list; I am posting this in case I didn't express the problem clearly (very possible). -- jss - Jon S.

Expressed this way, the answer is very simple: you can't do this in C in any portable way. (There is no guarantee that you can do it even in an unportable way.) C simply does not give you the ability to build argument lists yourself. There are a few kludges for awkward cases like printf, but no general primitives. -- 1755 EST, Dec 14, 1972: human | Henry Spencer at U of Toronto Zoology exploration of space terminates| uunet!attcan!utzoo!henry henry@zoo.toronto.edu
