Hashtable Synchronization to Ensure Thread Safety

by: Cyrus | last post by:

I have a question regarding synchronization across multiple threads for a Hashtable. Currently I have a Threadpool that is creating worker threads based on requests to read/write to a hashtable. One function of the Hashtable is to iterate through its keys, which apparently is inherently not thread-safe. Other functions of the Hashtable include adding/modifying/deleting. To solve the synchronization issues I am doing two things: 1. Lock...

Hashtable of Hashtables being accessed from multiple threads.

by: PAzevedo | last post by:

I have this Hashtable of Hashtables, and I'm accessing this object from multiple threads, now the Hashtable object is thread safe for reading, but not for writing, so I lock the object every time I need to write to it, but now it occurred to me that maybe I could just lock one of the Hashtables inside without locking the entire object, but then I thought maybe some thread could instruct the outside Hashtable to remove an inside Hashtable...

Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. 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,...
