关于这个问题,本质上是有一个词语你没有透彻理解,这个词就是所谓的线程安全,thread safe。 如果你不能理解线程安全,那么给你再多的方案也是无用武之地。 接下来我们了解一下什么是线程安全,怎样才能做到线程安全。 这些问题解答后,多线程这头大怪兽自然就会变成温顺的小猫咪。 可上图关小猫咪屁事! 关你什么屁事 生活中我们口头上经常说的一句话
time(), gettimeofday() and possibly localtime() are not thread safe functions.time() is, on some platforms at least, implemented by using gettimeofday(). 可重入函数 必然是 线程安全函数 和 异步信号安全函数; 线程安全函数不一定是可重入函数。(http://blog.csdn.net/jiange_zh/article/details/520...
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. ...

Thread Safety线程安全性 一般来说,cJSON不是线程安全的。 但在以下情况下是线程安全的: cJSON_GetErrorPtr从未被使用过(可以使用cjson_parse_end参数cJSON_ParseWithOpts) cJSON_InitHooks只在任何线程中使用cJSON之前被调用。 在所有对cJSON函数的调用返回之前,从未调用setlocale。 Case Sensitivity大小写敏感...
