linux gcc编程中如何得到某个文件对应的inode结构

   #include <sys/types.h>
       #include <sys/stat.h>
       #include <unistd.h>

       int stat(const char *path, struct stat *buf);
       int fstat(int fd, struct stat *buf);
       int lstat(const char *path, struct stat *buf);
看这些函数，就是用来取inode等信息的。

struct file *filp = filp_open(path, O_RDONLY, 0); if (!IS_ERR(filp)) {       struct dentry *dentry = dget(filp->f_dentry);       if (dentry)       {            struct inode *inode = dentry->d_inode;            dput(dentry);        }       filp_close(filp, NULL); }
