PTHREAD_RECURSIVE_MUTEX_INITIALIZER和PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP有什么区别？
[英]What is the difference between PTHREAD_RECURSIVE_MUTEX_INITIALIZER and PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP?
问题描述
When statically initializing a recursive mutex, what is the difference between 
静态初始化递归互斥锁时，有什么区别
static pthread_mutex_t foo_mutex = PTHREAD_RECURSIVE_MUTEX_INITIALIZER;
and 和
static pthread_mutex_t foo_mutex = PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP;
and why should I want the one instead of the other? 为什么我要一个而不是另一个呢？

"_NP" is meant as a hint that the feature is nonportable. “_NP”表示该功能不可移植。 In order to keep the hint there, you are best off to use the "_NP" version. 为了保持提示，最好使用“_NP”版本。
Other than that I suspect there is no difference. 除此之外，我怀疑没有区别。 Not 100% sure, though. 但不是100％肯定。
