All the File System definitions are in a header file, memfs.h. It works as following: MemFS is made of a collection of contiguous blocks, each one of 512 bytes in size.

INSTRUCTIONS TO CANDIDATES
ANSWER ALL QUESTIONS

In this assignment, you will implement some operations for a toy in-memory File System, MemFS. It has to keep all blocks in memory, not in a storage device.

All the File System definitions are in a header file, memfs.h. It works as following: MemFS is made of a collection of contiguous blocks, each one of 512 bytes in size.

These blocks are not in a storage device, but in user memory. The number of blocks is configurable when instantiating the File System. In MemFS there are two types of files, either regular ones (text files, images, etc), or directories (which can contain other files).

Both types of files are represented by a struct called a mem_inode. This struct contains information about the type of file, its last modification time, and its contents. Contents of a file are stored in other blocks.

For regular files, the content blocks will contain text, data, etc depending on the type of file, and for directories, the blocks contain directory entries. There are a set of pre-allocated blocks that contain all the inodes in the system, and we can identify those inodes by a number.
