(libxc error reporting is a bit of a mess, but this is the intention). So the caller here can assume that errno has already been set to something appropriate (probably ENOMEM) and it is fine to translate the NULL into a -1 since the overall function returns an int not a pointer. > and use goto err, otherwise you're leaking xs_fd. This is good advise and implies that rv should be set to -1 before the goto. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
