1. reentrant function A function is reentrant if it can be safely recursive or called in parallel. To become a reentrant function, the function cannot contain (or use) static (or global) data (to store state information during a function call), nor

Thread-Safe functions:When a function is called concurrently by multiple concurrently executing threads, it produces the correct result.reentrant functions :Re-entry can be repeated, meaning that the function can be interrupted.In multi-threaded or

Thread Safety : a function is called thread-safe (thread-safe), and it always produces the correct result when it is called repeatedly by multiple concurrent processes. If a function is not thread-safe, we say it is thread insecure (thread-unsafe).

Introduction:A set of concurrent threads runs in the same process context, with each thread having its own separate thread context, including thread ID, stack, stack pointer, program counter, condition code, and general purpose register. Each thread

Http://docs.sun.com/app/docs/doc/819-7051?l=zh "Multithreaded Programming Guide" An excerpt from the "Apue" POSIX and ISO c define errno as such a symbol, which expands into a modifiable integer left value (lvalue). This can be an integer that

This article mainly introduces the deadlocks, reentrant locks, and mutex locks in Python. although Python GIL problems in thread programming are commonplace, you can refer I. deadlock To put it simply, a deadlock occurs when a resource is called

I. reentrant Functions 1) What is reentrant? The reentrant function can be used concurrently by more than one task without worrying about data errors. Conversely, non-reentrant functions cannot be shared by more than one task, unless they ensure
