the server intended multithreaded server spawns new threads upon either producer or consumer connection via tcp. problem i'm getting stuck in wait state once producer client fills queue. snippet shows server's handling of producer connection. format of request producer sends put (item) reqline[0] = strtok (mesg, " \t\n"); if ( strncmp(reqline[0], "put\0", 4)==0 ) { item[0]=strtok(null," \t\n"); pthread_create (&pro, null, producer, fifo); pthread_join (pro, null); } so can see i'm creating new thread handles job of filling queue/detecting when empty. code within producer: queue *fifo; int i=atoi(item[0]); char*fullmsg="full\n"; fifo = (queue *)q; pthread_mutex_lock (fifo->mut); while (fifo->full) { //the problem block printf ("producer: queue full.\n"); send(conn_s, fullmsg,st

i'm having hard time finding answer this, such generic terminology, , it's possible question still difficult parse. have code variable representing amount of free disk space remaining percentage. want call function, use reverse amount in message user, i.e. amount of used space. can little math in function call? public sub myapp() dim nfreespace integer nfreespace = getfreespace displayusedspace 100 - nfreespace 'is valid? end sub private function displayusedspace(byval nusedspace integer) boolean msgbox("you have used " & nusedspace & "% of disk drive space.") end function yes, valid. although, write this call displayusedspace(100 - nfreespace) but, code work fine too.

after doing research, partially on stack overflow, decided try boost.log library andrey semashev. unfortunately, build boost.log library i have place in boost source tree , compile part of boost. blocker me, because have complicated building configuration. i want build boost.log standalone. i've found interesting thread on boost.log forum , method doesn't work me. instead of using boost.log, might suggest consider cpplog: https://github.com/andrew-d/cpplog it's header library based on google's logging library.

feel free massively re-word question. basically, i'm stripping out huge portion of large framework - involves lot of commenting. can find of later batch commenting , copy-pasting marker before each block this: //myinitials_remove /*if (this code rubbish) { comment out; }*/ i'd create function 1 button press or key combination batch comment out selected code , automatically place tag @ beginning. instead of opening comment being '//' or '/*' 'myinitials_remove//' or 'myinitials_remove/*' is possible? edit thinking it, wouldn't mind if every single line began 'myinitials_remove//'. i think looking this: public sub cstylecomment() dim selection textselection = dte.activedocument.selection selection.toppoint.createeditpoint.insert("//myinitials_remov" & vbcrlf & "/*") selection.bottompoint.createeditpoint.insert("*/") end sub maybe version more suitable (aut

you know how php errors show @ top of page. there way suppress , turn in $var? place somewhere in page. yes, set own error handler intercept , error besides outputting them wherever occur. don't think it's useful display php errors elegantly on page. php errors not meant pretty, they're not meant occur @ all. if see one, should jarring possible , should fix possible. they're meant during development. trying pretty them spending time on wrong part of code. in production, errors should logged log file , not visibly output on page @ all.

okay, trying make site using zend framework on php , jquery. make ajax call page 1 of controllers , controller echos code, jquery never "succeeds". got: jquery ajax call: $('.homelink').click(function() { $.ajax({ url: '/index/ajax/page/index', type: 'post', success: function(result){ alert(result); } }); }); the controller echo's following string: <p>home page content here</p> the problem function never called upon success send alert. any help? thanks. update: i discovered ajaxcontext switch. jquery call bit different. using url '/index/index/format/html'. the zend controller being call correctly however, nothing being returned still. console replies internal server error (code 500).
