|
|
* off_t r_super(int *block_size);
|
|
* Initialize variables, returns the size of a valid Minix
|
|
* file system blocks, but zero on error.
|
|
*
|
|
* void r_stat(ino_t file, struct stat *stp);
|
|
* Return information about a file like stat(2) and
|
|
* remembers file for the next two calls.
|
|
*
|
|
* off_t r_vir2abs(off_t virblockno);
|
|
* Translate virtual block number in file to absolute
|
|
* disk block number. Returns 0 if the file contains
|
|
* a hole, or -1 if the block lies past the end of file.
|
|
*
|
|
* ino_t r_readdir(char *name);
|
|
* Return next directory entry or 0 if there are no more.
|
|
* Returns -1 and sets errno on error.
|
|
*
|
|
* ino_t r_lookup(ino_t cwd, char *path);
|
|
* A utility function that translates a pathname to an
|
|
* inode number. It starts from directory "cwd" unless
|
|
* path starts with a '/', then from ROOT_INO.
|
|
* Returns 0 and sets errno on error.
|
|
*
|
|
* One function needs to be provided by the outside world:
|
|
*
|
|
* void readblock(off_t blockno, char *buf, int block_size);
|
|
* Read a block into the buffer. Outside world handles
|
|
* errors.
