Currently, the functions return a pointer to the destination buffer on success or NULL on failure. Not only does this kind of error handling look quite alien in the context of libvirt, where most functions return zero on success and a negative int on failure, but it's also somewhat pointless because unless there's been a failure the returned pointer will be the same one passed in by the user, thus offering no additional value. Change the functions so that they return an int instead. Signed-off-by: Andrea Bolognani <abologna@redhat.com> |
