21.1 Dynamic TLS21.1.1 Why use thread-local storageWhen writing a multithreaded program, you want to store some thread-private data, and we know that the data belonging to each thread is private, including the thread's stack and the current register, but both of these are very unreliable, and the stack is changed when each function exits and enters, and the regis

each thread has its own clear log file, each thread has only a simple log case, so that the log system has a simple and clear and efficient features and is applicable to single-threaded and multi-threaded applications. The multithread log system described in this paper is a realization based on C + + and Boost library, which is very useful for the implementation of the log system in multithread environmen

1. Reasons for using thread-local storageWhen we want the global variables of this process to become thread-private, instead of shared by all threads, that is, when each thread has a copy, the thread-local storage (tls,thread loca

1. Local thread storage (Windows, Thread Local Storage) TLS is a mechanism through which the program can have global variables, but is in a state where each thread is different. That is to say, all threads in a process can have global variables, but these variables are actua

Thread-local Storage (thread locally Storage), referred to as TLS, provides a way to store thread-private data that is not visible to other threads by each thread's private data. Chromium is a multi-process multithreaded architecture browser that creates up to 30 threads, ma

Windows TLS (thread local storage)I. TLS description and classificationWe know that in a process, all threads are sharing the same address space. So, if a variable is global or static, then all threads are accessing the same part, and if one thread modifies it, it affects all other threads. However, we may not want this, so it is more recommended to use a stack-b

InnoDB Storage Engine OverviewThe InnoDB storage engine is the first MySQL storage engine to fully support acid transactions, characterized by row lock design, support for MVCC, support for foreign keys, consistent non-lock read, and design for the most efficient use and use of CPU and memory.2.

Simple analysis and use of Thread Local Storage (TLS) In multi-threaded programming, if multiple threads need to share access to the same variable, the variable can be declared using the keyword volatile. If a variable does not want to share access among multiple threads, so what should we do? Ha, this method is TLS, local thread

The following descriptions and examples are excerpted from the Internet, but the content has been sorted and edited. "What is the function of Thread Local Storage? It is mainly used to avoid conflicts caused by multiple threads accessing the same global variable or static variable at the same time, especially when multiple threads need to modify this variable at the same time. To solve this problem, we

function is consistent with the parameters of the DllMain function, so ReasonForCall does their representation mean the same thing?For example dll_process_attach , a DLL creation or process creation.Also, a program first create a process, TLS once, and then create the main thread, supposedly should be TLS once, how not it. The main function is running on the main thread.2. I feel like this is actually the

The log buffer is flushed to disk, even though the transaction has not yet been committed (always), which explains why

The C + + runtime provides TLS (thread-local storage), which can be associated with the executing thread when multithreading is not yet produced. The Strtok () function is a good example. Along with it are strtok_s (), _tcstok_s (), and so on, in fact _tcs is another form of WCS, representing the wide character store, _s is a security function defined by Microsof
