So, the final version of the function would look like:
static bool qemu_graphic_console_is_multihead(QemuGraphicConsole *c)
{
QemuConsole *con;
QTAILQ_FOREACH(con, &consoles, next) {
if (!QEMU_IS_GRAPHIC_CONSOLE(con)) {
continue;
}
QemuGraphicConsole *candidate = QEMU_GRAPHIC_CONSOLE(con);
if (candidate->device != c->device) {
continue;
}
if (candidate->head != c->head) {
return true;
}
}
return false;
}
