c - OS X: Generate core dump without bringing down the process? -

I know how a core dump is generated on OS X when a process crashes, but I Actually what a process to do, produces a core dump, then start the process again (without killing it). A long time ago (maybe a year and a half years ago) I had a code that would have to do this ... it is used to connect OS X kernel libraries to a process, its All thread reads states and memory, and writes in a MchOo file on disk. It did great work (and what I actually see), but now I can not get that code for my life. I remember that this code was somewhat related to the OS X System Internal Book, but it Just remember a vague one. Does anyone know the code about which I am talking about and can talk to me on that? If someone does not know any good way to do this with some example code? EDIT: Here is the answer. Information: Program that I believe That you are looking for : Specifically: / P> / * Unix third edition, beginning in approximately 1973 / / * Ken / Sig. C / core () {int s, *...

How is MSBuild Incremental Building Different from Copy with SkipUnchangedFiles=true? -

If I have an MSBILD target that just copies the files, then the incremental building using the copy function and the setting Why would it be better SkipUnchangedFiles = true? Who said this? The only reason you can think is that if you later increase your goal to accomplish other tasks, just copy it.

C++ standard/de facto STL algorithm wrappers -

Is there a standard / real standard wrapper around a standard algorithm that explains the beginning and end of containers Let me show you what I mean with the code: // instead of specifying std :: copy (vector.begin (), vector.end (), output) Instead of specifying; Write as xxx: copy (vector, output); I know that it can be easily written, but I am particularly looking for something ubiquitous. Thank you. It has an extension of the Boost Range Library named RangeEX, which includes range rappers for all stell algorithms, It has recently been accepted in Boost and hence it is not yet in the "official" release (1.41). Unless this change can happen, you can do it with boost vault. I do not know that this will ever be a part of the C ++ standard, but the fact that Boost is in it means that this de real standard

.net - How to make sgen.exe keep the version of the assembly? -

I want to create a serialization assembly for my assembly sgen this is ok, but I Can not understand how to specify the same version as the serialization assembly in the form of a source assembly. Any thoughts? sgen by default, take source assembly version, it is quite reasonable . Here's how I'm running, nothing special: "... pathToSDK ... \ Microsoft Visual Studio SDK \ sgen.exe" / force / Assembly: "$ (target)" / compiler: "\" / keyfile: $ (projectdair) .. \ key.snk "\" / compiler: / deliensen - / force- Existing serializer assemblies to overwrite / assembly - For path assembly, I run it in post-build event in VS project settings, so I have the $ (TargetPath) variable I use

java - Lazy loading in Hibernate -

My Java Web application uses Hibernate to ORM In some of my objects, I use lazy loading until then To get it until I need it. The problem is that I load the initial object in a session, and after that the session is destroyed when I try to resolve the lazy-loaded collection in my object later, then the following error Receives: org.hibernate.LazyInitializationException: Failed to start a collection of role: common. Model.impl .User.groups, no session or session closed I tried to add a new session with the archive and then tried to solve it, but it was a Only gives results. Does anyone know how to solve lazy collection after the original session is over? Thank you ... - Steve three Option: call Hibernate.in initialize (..) whenever your archive will be disconnected from the current session Announce as the collection FetchType.EAGER . merge (..) your user object back in new session

java - Regex to split nested coordinate strings -

I have a string of format "[(1, 2), (2, 3), (3 , 4)] " , with an arbitrary number of elements, I'm trying to divide it by commas that separate the coordinates, i.e., (1, 2) , (2, 3) , and to get (3, 4) . Can I do this in Java Reggae? I'm totally communicating but it is quite powerful to hope for Java reggae. If it is not, can you give an alternative suggestion? You can use it for string string = " [(1, 2), (2, 3), (3, 4)]; String = string.substring (1, string.length () - 1); // Get rid of strings string [] parts = string. Split ("(? & Lt; = \\)) (, \\ s *) (? = \\ ()"); For (string part: parts) {part = part.substring (1, part.length () - 1); // Get rid of brackets string [] coords = part.split (", \\ s *"); Int x = integer.center (quotes [0]); Int y = integer.centre (coars [1]); System.out.printf ("x =% d, y =% d \ n", x, y); } (? & Lt; = \\)) means it should be before ) . (? = \\ () means that it sho...

In C++, are static initializations of primitive types to constant values thread-safe? -

That is, will any of the expected environment be expected to be executed properly? int dostaf (zero) {static int somevalue = 12345; Return some value; } Is it possible to call many threads, and to return whatever was wasted on and somevalue before the execution begins To call? from C ++ standard, volume 6.7: A local object of type POD ( 3. 9) With static blocking period, starting with the initial stability, before the block is first entered. This means that the function-level static object has entered the function for the first time, not necessarily when the process is fully initiated. At this point, many threads can run well.
