ftest.c

这是一个同样来自贝尔实验室的和UNIX有着渊源的操作系统, 其简洁的设计和实现易于我们学习和理解

#include <u.h>
#include <libc.h>
#include <auth.h>
#include <fcall.h>
#include "9p.h"

void
main(void)
{
	Tree *t;
	File *hello, *goodbye, *world;

	t = mktree();

	hello = fcreate(t->root, "hello", CHDIR|0777);
	assert(hello != nil);

	goodbye = fcreate(t->root, "goodbye", CHDIR|0777);
	assert(goodbye != nil);

	world = fcreate(hello, "world", 0666);
	assert(world != nil);
	world = fcreate(goodbye, "world", 0666);
	assert(world != nil);
	fdump(t->root, 0);

	fremove(world);
	fdump(t->root, 0);
}
