Using qapi visitors to parse the command line. Used by -blockdev and
-display (and maybe others meanwhile). See parse_display_qapi().
I think Daniels suggestion was to do that in the backends ...
More than just that - I was thinking of this series:
http://lists.gnu.org/archive/html/qemu-devel/2017-10/msg00209.html
In that there is no QemuOpts, or getopt(), etc. You end up using QAPI
for the entire argv parsing procss:
QAPIOption *qopt;
qopt = qapi_options_parse(argc, argv);
for (i = 0; !qopt[i].cnt; i++) {
switch (qopt[i].type) {
case QAPI_OPTION_KIND_NODEFCONFIG:
defconfig = false;
break;
case QAPI_OPTION_KIND_NO_USER_CONFIG:
userconfig = false;
break;
...etc...
}
Regards,
Daniel
