C99 guarantees that 'return int' in a bool function will return 0 or 1; but because we are using gnulib's <stdbool.h>, we can't take that shortcut (gnulib's implementation of stdbool on top of C89 compilers might return > 1, with potential confusion downstream when you have a value out of range of bool). But what you have is is correct, so up to you if you go for a shorter representation. ACK. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
