qt - Working with multiple network sessions simultaneously -

how can send requests on 2 network interfaces using qtwebkit? test code seems utilize same interface. question is:

does webkit care qnetworksession?: if not, how can forcefulness webkit utilize specific network interface?

sample code:

// main.cpp qlist<qnetworksession*> sessions; qlist<qnetworkconfiguration> configs = configmanager.allconfigurations(qnetworkconfiguration::active); foreach (const qnetworkconfiguration& config, configs) { sessions << new qnetworksession(config); qdebug() << "preparing network session on " << config.name(); } foreach (qnetworksession* session, sessions) { qwebpage* page = new qwebpage(); pageviewer* viewer = new pageviewer(0); qobject::connect(page,signal(loadfinished(bool)),viewer,slot(showresults(bool))); viewer->setpage(page); page->setnetworkaccessmanager(&accessmanager); session->open(); qdebug() << "internal ip reported interface is:\t\t" << session->interface().addressentries().at(0).ip().tostring(); session->waitforopened(); page->mainframe()->load(qurl("http://wtfismyip.com/text")); session->close(); } // page-viewer.cpp void pageviewer::showresults(bool results) { qdebug() << "external ip reported `http://wtfismyip.com/text' is:\t" << this->page->mainframe()->toplaintext().trimmed(); }

qnetworksession defines if interface available, has no effect on routing of packets.

qtwebkit passes network connection through qnetworkaccessmanager::get, , through qtcp/sslsocket, don't think uses qabstractsocket::bind used define interface should used.

so sadly i'd can't controlled through api, might easier tweak @ os routing level unless you're willing modify qnetworkaccessmanager's code.

assembly - What is the addressing mode for ld, add, and rjmp instructions? - hey guys know ldi (load immediate) addressing mode set immediate , st instruction addressing mode set index. however, have no thought others curious are! thanks :) the addressing modes explained in instruction set, in first few pages. in table of instructions see operands instruction determine addressing mode. mode indicated arguments assembly instruction. for example, ld had several different ways of operating, depending on arguments. 1 of them ld rd,x d number of register, such ld r3,x . ld r3,-z else (although both indirect addressing). rjmp k relative addressing, jumping pc + k + 1. add rr,rd direct register addressing. result contained in rd. assembly avr instructions
