操作系统中的系统调用ID定义在/usr/include/asm/unistd.h中(内容如下),其中32位系统使用<asm/unistd_32.h>,64位系统使用<asm/unistd_64.h>。 如golang中的SYS_SOCKET系统调用ID为41,对应redhat系统的定义为#define __NR_socket 41 //asm/unistd.h #ifndef _ASM_X86_UNISTD_H#define_ASM_X86_UNISTD_H/...

非常典型的方式就是,在访问共享数据(例如数组、Map、或者某个结构体或对象)的时候,通过锁来访问,因此,在很多时候,衍生出一种方便操作的数据结构,叫做“线程安全的数据结构”。例如Java提供的包”java.util.concurrent”中的数据结构。Go中也实现了传统的线程并发模型。 Go的CSP并发模型,是通过goroutine和channel来...
