/*
    NAME
      open  a file or device

SYNOPSIS
       #include <sys/types.h>
       #include <sys/stat.h>
       #include <fcntl.h>
        
        参数列表，参数列表中的每一个参数叫做形参
       int open(const char *pathname, int flags);
        参数：
        pathname：要打开的文件的路径或者文件名
        flags:  打开的标志
            只读：O_RDONLY
            只写：O_WRONLY
            可读可写：O_RDWR
        
        返回值：file descriptor文件描述符
            成功: 返回打开的文件的文件描述符
            失败：返回-1
    

NAME
       write - write to a file descriptor

SYNOPSIS
       #include <unistd.h>

       ssize_t write(int fd, const void *buf, size_t count);
    参数：
        fd：要写入的文件的文件描述符，open的返回值
        buf: 一个容器，用来装需要写入文件中的内容的(一个指针，指向需要写入文件的内容)
        count：需要写入文件的内容的字节数！！！

 NAME
       mmap, munmap - map or unmap files or devices into memory

SYNOPSIS
       #include <sys/mman.h>

       void *mmap(void *addr, size_t length, int prot, int flags,
                  int fd, off_t offset);
                  
            addr: 表示您要映射到进程哪个地址上去。一般为NULL,让操作系统    
                    自动分配一个地址。
                    
            length:要映射文件或设备多少字节，映射长度。会自动向上取PAGE_SIZE(4k)
                    的整数倍。
            prot: 映射区域的权限，应与打开文件时设定的权限一致，因为操作该映射区域    
                    实际就是操作文件
                    PROT_READ:映射区域为只读
                    PROT_WRITE:映射区域为读写
                    PROT_EXCE: 映射区域可执行
                    PROT_NONE: 映射区域没有访问权限
                    
            flags: 映射标志
                    MAP_SHARED: 共享的。对映射区域的操作直接操作在文件上。
                    MAP_PRIVATE:私有的。对映射区域开了一个私有的缓冲，对映射区域的操作不直接操作在文件上。
                  
            fd: 文件描述符，表示您要映射哪个文件或设备
            offset: 偏移量，表示从文件哪个位置开始映射。这个地方必须为PAGE_SIZE(4096)的整数倍。
            
        返回值:
            成功返回映射区域的首地址
            失败返回MAP_FAILED ,同时errno被设置。
                

            munmap解映射
       int munmap(void *addr, size_t length);
         
        read用来从fd指定的文件中，读取count个字节到buf指向的内存
        ssize_t read(int fd, void *buf, ssize_t count);
        
            返回值:
                > 0: 表示实际读到的字节数
                =0: 文件读到末尾
                <0: 出错，同时errno被设置。
