Re: [Libguestfs] [PATCH libnbd] generator: Add SizeT type, maps to C size_t.

Question: Should nbd_opt_list() return RSizeT instead of RInt, as it is returning a count of times the callback was called? The same question would apply to my upcoming nbd_opt_list_meta_context(). Changing a return type from 'int' to 'ssize_t' can result in an ABI change (32- vs. 64-bit return on some platforms), which may be too risky, even though 1.4 is still fairly new that we are unlikely to break anyone in practice. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3226 Virtualization: qemu.org | libvirt.org
