In terms of documentation, docs/misc/xenstore.txt already does a fine job. And I think a xen/public/... header is the right place for the limits, since it is a general documented protocol-level constraint, rather than a constraint of the particular client library (which is the scope of xs.h itself). -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
