Re: HTHostEventimeout: How do u cancle a timer

MessageI guess you are right. But it is strange that Timeout does not get deleted esp in my case where I am termintating the libwww library at end of each call and initialising it again all over for subesquent request...
By the way how did you found out about the timeout of 30 secs?

  On the HostEventTimeout, I have a general question

  I have a similar application that launches a request recursively. What I do notice is that the timer that is started for a request (or rather the host) is not cancelled when the request is complete. It times out after the pre determined 30 seconds. IF we had launched another request then a new timer is started.

  My questions is : shouldn't the old timer (with the first request) be cancelled. I can see that it times out at the end of 30 seconds and tries to execute the call back function. If there is a method to do that can someone please point me to it. I would imagine that the library should take care of this automatically

  Thanks Raj

    Hi All,

        I have written a piece of code something like this and I am calling the function xrayhttpget after a fixed time interval repeatetively .But I have encountered a problem in this
    Suppose I give a valid uri of some html document and as I said my program logic will continuosly loop and try to fetch this document in each iteration .Also I have specified the 
    time gap between the successive requests is 3 seconds then during the second iteration my program gives segmentaion fault and it occurs due to the HTHost_setEventTimeout(3000);
    call in the code.Could anyone explain me why this could occur?

    Thanks
    Sandesh
