Hi, all! There is some work happening on new PV protocols: sndif [1], displif [2], PV calls [3] and the common part of those is that error/status codes must be returned as a part of a response packet. For that Konrad suggested [1] (and Stefano already used in [3]) POSIX to be employed here instead of defining protocol specific error codes. The problem I see here is that POSIX only defines names of the errors, but not values [4]. So, in order to use POSIX one still needs to definethe values (names must be the same, but values may differ for different OSes). So, the question is what would be the best option to a) have those numbers defined in OS agnostic way b) have those defined for all PV protocols Stefano has already defined the error code values in his work [3], but for other protocols this should be reimplemented again. Thank you, Oleksandr [1] https://marc.info/?l=xen-devel&m=148528530727366&w=2 [2] https://marc.info/?l=xen-devel&m=148239440624498&w=2 [3] https://marc.info/?l=xen-devel&m=148530334732400&w=2 [4] http://pubs.opengroup.org/onlinepubs/007908799/xsh/errno.h.html _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx https://lists.xen.org/xen-devel
