学习：Linux之管道

一、管道学习笔记

二、代码（结合父子进程，子进程写数据，父进程读数据）

//子进程写数据，父进程读数据
#include<stdio.h>
#include<string.h>
#include<assert.h>
#include<fcntl.h>

int main()
{
	int fds[2];
	pipe(fds);
	pid_t n = fork();
	assert(n != -1);
	if(n == 0)
	{
		close(fds[0]);
		printf("please input: ");
		char buff[128] = {0};
		fgets(buff,127,stdin);
		write(fds[1],buff,strlen(buff)-1);
		close(fds[1]);
	}
	else
	{
		close(fds[1]);
		char buff[128] = {0};
		read(fds[0],buff,127);
		printf("father read data : %s\n",buff);
		close(fds[0]);
	}
}
