It is more efficient to use a global variable than to pass a parameter to a function. This eliminates the need to push the parameter onto the stack before the function call and pop it back off once the function is completed. In fact, the most efficient implementation of any subroutine woul...

The localeconv function declared in locale.h now works correctly when per-thread locale is enabled. In previous versions of the library, this function would return the lconv data for the global locale, not the thread's locale. If you use per-thread locales, you should check your use of loc...

在C 语言中,结构体(struct)是一种用户自定义的数据类型,它允许你将多个不同类型的变量组合在一起。结构体通常用于表示一个记录或对象,其中包含多个相关的数据成员。 结构体的定义 定义一个结构体需要以下步骤: 使用struct 关键字:定义一个新的结构体类型。
线程池(thread pool)技术是指能够保证所创建的任一线程都处于繁忙状态,而不需要频繁地为了某一任务而创建和销毁线程,因为系统在创建和销毁线程时所耗费的cpu资源很大。如果任务很多,频率很高,为了单一一个任务而起线程而后销线程,那么这种情况效率相当低下的。线程池技术就是用于解决这样一种应用场景而应运而生的。
