Methods

§int init(&BlockDevice dev)source · definition

Initialise this context in place from a block device (copied into dev). Returns 0 on success.

§int read_block(unsigned long block_no, []unsigned char buf)source · definition

Read block block_no into the first block_size bytes of buf (-1 if it is shorter).

§int read_inode(unsigned long ino, &Ext2Inode inode_out)source · definition

Read inode ino into inode_out. Returns 0 on success.

§unsigned long read_file(unsigned long ino, unsigned long offset, []unsigned char buf)source · definition

Read up to buf.len bytes of inode ino's data at byte offset.

§int open(const &char path, int flags, &VfsNode node_out)source · definition

§unsigned long read(unsigned long inode, unsigned long offset, []unsigned char buf)source · definition

§generic<T> int readdir(unsigned long inode, fn void(&VfsNode, ?&T) cb, ?&T user)source · definition
