内存中,开辟的一个二进制模式的buffer,可以像文件对象一样操作它,当close被调用的时候,这个buffer会被释放 file-like对象:类文件对象,可以像文件对象一样操作,socket对象,输入输出对象(stdin,stdout)都是类文件对象

• stderr-标准错误流,大多数环境中输出到显示器界面。这是默认打开了这三个流,我们使⽤scanf、printf 等函数就可以直接进行输入输出操作的。 stdin、stdout、stderr三个流的类型是: FILE* ,通常称为文件指针。 C语⾔中,就是通过 FILE* 的⽂件指针来维护流的各种操作的。
[ w ]代表可写(write): 可以修改,但是不代表可以删除该文件,删除一个文件的前提条件是对该文件所在的目录有写权限,才能删除该文件. [ x ]代表可执行(execute):可以被系统执行 (2)作用到目录: [ r ]代表可读(read): 可以读取,ls 查看目录内容 [ w ]代表可写(write): 可以修改,目录内创建+删除+重命名...

File descriptor 0, 1, and 2 are allocated to the first three files that have descriptors allocated to them. If an application writes to file descriptor 1 assuming it is stdout, the result will not be as expected. Any API that assumes stdin, stdout, and stderr are file descriptors 0, ...
