Presumably the returned buffer is static.
You could use a static pointer to a buffer which is reallocated on
each call; from the exterior the semantics would be close to
static char *buf = NULL;
buf = realloc(buf, whatever size is required this time);
You'll be fine as long as the calling code does not assume the
function returns a constant pointer.
