When an application crashes...

Hi all,

I'm working on a Linux machine and using g++. I'm developing an
semaphore module for a number of applications in the system.

My question scenario is, an application can lock a resource which is
shared memory segment in this case, after they locked a segment and if
they somehow crash then the lock won't be released because the
application locked the resource is dead.

I hope there must be a way to release the lock so solve this problem
even the application is crashed unexpectedly.

Any idea?

best regards,

Alex D. B. Kim

Hi folks I'm a bit of a newbie here, though I've tried to appropriately research this issue before posting. I've found a lot of questions, a few answers that don't really answer quite what I'm looking for, but nothing that really solves or explains all this. I'll admit to being stumped, hence my question here. I'm also trying to make this post as clear and detailed as possible. Unfortunately, that means it's come out like a book. I...

I observe the following strange behavior of my application. Let say we have managed application MyApp.exe which depend on a few assemblies MyAssembly1.dll, MyAssembly2.dll and MyAssembly3.dll. The assemblies I mentione have strong names. I build the exe and all assemblies on my computer and install assemblies to GAC. I run MyApp.exe, test it and everything is OK. Then I copy all executable files (exe and dll) to our network server.

Hi all I have a multi-threaded application running on AIX 5.3 and DB2 8.2 that takes snapshots from different threads. Each thread that takes snapshot allocates an application context (using sqleBeginCtx), and frees it when the thread goes down (using sqleEndCtx). The application runs well for a while and after a couple of hours it crashes when it tries to get the snapshot size. After the application crashes at the first time, it keeps...

I was reading the code of FFmpeg and it seems that they use malloc just too much. The problems and dangers of malloc are widely known. Malloc also has some overhead (although I don't know what is the overhead of automatic variable sized arrays, I suspect it is smaller than that of malloc), although I'm not too worried about it. I was thinking that, with C99's variable length arrays, malloc shouldn't be needed most of the time. But I'm...

Hey there, this will be somewhat a long post, but any response is appreciated! I have done many PInvoke in the past from C++ to C#, but I did PInvoke within C# not C++/CLI.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
