If you're waiting for another thread to do something I'd agree. What I run into all the time though is that I want to poll a device every so often so I want to surrender my thread for x amount of time. Scanned by McAfee GroupShield {X3BTB534}

Using serialization for replication
by prez＠neuromancy.net 10 Apr '06

10 Apr '06

Hey, I want to use serialization for some kind of active replication, however the biggest barrier to this is the fact that serialization does not allow me to put the same object into the stream twice. To be more precise, I want to be able to serialize both to a network and to disk, and I very much like the elegance of the serialization approach (plus the fact it can re-create pointer references, arrays, and such). So my questions are: a) How difficult would it be to be able to allow an object to be serialized twice, where the second copy would more or less do an operator= (instead of creating a new object) on the first copy on deserialization. b) How difficult would it be to have more or less an 'appending' serialization stream - ie. I deserialize what I have previously stored on disk, and then continue to append to the serialization stream (which appends to the file from then on), making my serialization more or less unbounded. c) Is there currently an unbounded serialization stream? I mean, obviously the XML stream will not be 'complete' until you close the serialization stream and it can append any close tags it needs to, however if I wanted to continually write to a stream throughout the time my program is running, and if it crashes, be able to use that to get back to the state I was in, is it possible? I realize that in some respects this is kind of hammering a square peg into a round hole, since serialization seems to have been designed for 'one-short rights', but serialization and replication type functionality is very similar in nature. -- PreZ :) Death is life's way of telling you you've been fired. -- R.

Re: [boost] MultiArray warning under /Za

Ronald, Thanks for changing it. Just to clarify, this is why its happening: typedef int T; int f(int T); <-- using T as a parameter when its previously declared as a type is a no-no under strict conformance(?)

I'd like to second that request, needing to use the win32 Sleep just kills the portability. My workaround for yielding is - #if defined _MSC_VER || WIN32 # include <windows.h> // for Sleep # define MILLI_SECOND_SLEEP(value) (Sleep(value)) #else # include <unistd.h> // for usleep # define MILLI_SECOND_SLEEP(value) (usleep(value * 1000)) #endif but that's just a hack, it really should be in the library.

[FYI] RCF 0.2
by Jarl Lindrud 10 Apr '06

10 Apr '06

Hi all, I just thought I would announce that I've released v. 0.2 of RCF, a portable C++ IPC framework. It makes extensive use of boost, including Boost.Threads, Boost. Serialization, and the recently accepted asio library, so maybe people on this list will find it of interest :) http://www.codeproject.com/threads/Rcf_Ipc_For_Cpp.asp /Jarl.

[review assessment] Property tree library
by Thorsten Ottosen 10 Apr '06

10 Apr '06

Dear all, I have studied Marcin Kalicinski's Property tree library and its documentation. (For those who are interested, you may look at the library in the boost sandbox under the property_tree folders.) For a few weeks, Marcin has enhanced and simplified the interface. I now find the library fit for a review. Rewiew Wizzards, please arrange for a slot in the review queue. best regards Thorsten

boost::noninheritable class (was Re: Sealed C++ class)
by Vladislav Lazarenko 10 Apr '06

10 Apr '06

Hello, dear community. I have uploaded the code to the vault - "Generic Programming/noninheritable.zip" (http://boost-consulting.com/vault/index.php?action=downloadfile&filename=no…) The library, some documentation, examples and MSVC project files are present. It would be great if you will include this small library to official boost distribution. If no, let interested people download and use it anyway. Unfortunately, I can test it only with MSVC 7.1 now. So any help is welcome. Please review. Thank you very much for time taken to read this message and probably the code. Regards, Vladislav Lazarenko.
