And when you did, I pointed out that this approach would make it impossible to represent an empty argument, as two successive NUL characters would indicate the end of the stream. Also, I really don't think this makes the interface "simple"; it makes it obscure and baroque and increases the likelyhood that the implementation will be buggy. > I think a varargs approach would be easier to use.

The proposed interface does have the advantage that, like system(3C), it blocks until the child process exits and automatically collects the exit status. -- Jeff
