I just wanted to avoid introducing a lot of functions which could be

this capability from the upper layers?

well that's just for simplicity.

But when I was looking at the libxl_sprintf thing, I realized that all
the information in the info structure is static and will never change
during runtime. Am I right? If so, we can solve this whole thing by not
only storing the strings in libxl_ctx, but the whole structure. The
first call to the function would query all the members, subsequent calls
would just return the pointer. This avoids duplication should the
function be called multiple times. It would be automatically freed when
destroying the xl context.
What do you think of this?
