The concept of re-entrant code is slightly different from thread safe code. Usually in a single thread of execution if a function is called then before the completion of execution of that particular function, th
[https://mp.weixin.qq.com/s/ydhK8HYuRD0lZazPsPxsvg] c/c++语言具备一个不同于其他编程语言的的特性,即支持可变参数。 例如C库中的printf,scanf等函数,都支持输入数量不定的参数。printf函数原型为 int printf(const char *format, …); printf("hello world");///< 1个参数printf("%d", a);///...

The similar situation may occur also in Trivial Threads while setting up some important controlling object property (or variable) used in the childThread by both parent threads concurrently. For this reason, a concurrency-handling-of-one-object design has to be carefully prepared. This kind of ...
zlog is a reliable, high-performance, thread safe, flexible, clear-model, pure C logging library. Actually, in the C world there was NO good logging library for applications like logback in java or log4cxx in c++. Using printf can work, but can not be redirected or reformatted easily. ...
