Well I have One thread per Connection, but use WSAAccept to limit it to a reasonable number. I also have (on a Seperate thread) a Garbage Collection Service, that kills stale sockets. Any Sockets, not Kicked within a period, get Closed, the thread running it also gets closed.
The Socket (or Thread) gets kicked when traffic passes tru it, and a new period starts.

Each WSAAccept(...) is not sent off into the dark on a New thread, and a New Socket. The situation is carefully monitored, and the Callback in WSAAccept() will return 'CF_REJECT' if Too Many Sockets are open already.

Thanks,
With PARANOID turned on I thought I created a Pointer on the Local Stack, pointing to a Global Object This pointer is passed to the thread's stack, but still points to the same global object. I take it that all that is done when 'CreateThread' returns. MS Documentation states specfically that 'CreateThread' may return before the Newly Started thread completes( Otherwise 'CreateThread' would be pointless)or even before it commences!

I had Bad feelings about the code without 'PARANOIDE', and you confirm my bad feelings about it. The problem with synchronisation objects is, that I would have to apply the Lock in the Parent thread, and release it from the Child Thread. This is Something that does not sound right. (Having said that, maybe it is perfectly acceptable).

Apart from that, what I'm trying to do is not exactly breaking the mould. Useage of the 'CreateThread' function is peppered through all MS Apps.
I can only assume that they made it 'Usefull'. Unless if anyone comes up with a different Idea, I will for now assume that You're right in considering the 'PARANOIDE' option as threadsafe.

Thanks;

Regards :)

QQQ

How can a Single threaded app endup creating an unlimited number of sockets! I do not understand this at all! Surely a single threaded function can count the number of created sockets in a single global variable. (Does not need protection, because there is only one thread.) The CallBack of WSAAccept can reject the new socket, if too many are open.
At any rate, this is a latter day issue. For now I just want to establish basic connectivity.

Regards,

Bram.

Well, One thing at a time. I'm at experimental stage 0, and the first concern is what type of incantations are required to ensure that after the 'send(h_sockClient...)' , and going round the loop, 'listen(hSock,100)' works properly again. I'm debuging this with one client, and efficiency does not (yet) come in to it. I would have thought that for this testing purpose, one thread should suffice.

enhzflep below got it right!

Solution 1 fails because the Download is in an ISO Format, for which I have No Drivers

Solution 2 at least gives me the Header File.( From Linux Wine) I am aware that Headers cover Libraries, but I am also aware that most of the API is already included in Windows Libs.

I am already using that. However, that still decorates the name with a leading underscore. i.e. Foo() becomes _Foo. How do I loose that leading Underscore.

It is NOT the Computer name. It appears to be the name of my email host. (in my case the email host provided by AOL). I assume this can be found somewhere in the registry, the question is 'WHERE'.

BTW, Where is the User Manual for all this.

Is This then the Correct way of doing it?

Prety Ugly(Not your Fault), I just hate to have to write text in a Letterbox size Comment Box! Reminds me of 'edlin'.
And why should you not receive notification when I say Thanks and Confirm Usefullness. (Beats Me!)

Thanks for pointing out the error of my ways.
Hope to remember Next Time, but Old Habits die hard!

Sory, Maybe I should have answered here. This New CP Interface is still Strange to me! The workings have become obscure.

Bram van Kampen 15-Jan-11 21:10pm View

I'd gladly oblige if you just explain what you mean...

Well, it confirms my suspicions that all bets are off. So, I'm going to do it by Hand! fread the file in bin mode, Copy it with all '/r/n'contracted to single '/n', process it, and send it out again with each '/n' replaced with a '/r/n.
(Sorry Slashes run the Wrong Way, The CP Editor deletes the Correct Slashes)

It comes back though to what I said earlier, I never accused Microsoft of inventing the concept. At the time they did not have the foresight of perpetuating a problem. If MS had not adopted the termination, it would have been assigned to history a long time ago, along with things like the Dollar Terminated String, invented by Microsoft, which was famous in MS Dos 2. Thanks and Regards, Bram

No, fread is very much a standard library function,available both in 'C' and 'CPP' and must be supported by Microsoft, if they claim (as they do) that their compiler and API's comply with relevant ISO Standards. The standard stipulates that fread should be equivalent to a number of fgetch()calls. This would Translate things automatically. My version of the MS Library does not seem to support that.

Why would nobody use fread and fwrite in CPP. I use it daily in CPP and MFC Programs.

Bram van Kampen 26-May-10 19:31pm View

Well I still use MFC42, and it still works! (despite it being disconinued) In my last (9 year old project) I never used exceptions. I never needed them, Error conditions were propagated down the line in my code. It was Hard Work, as it involved a total of 12 modules.

I want to do it different this time.

Bram van Kampen 8-May-10 20:28pm View

you answered my question correctly, which led me to:
'http://www.codeproject.com/KB/dialog/pretransdialog01.aspx?msg=1897183'

(Sorry tried several times, but, cp does not allow to ad links.)

Issue Resolved!!, and Many Thanks
