Mumufs is a virtual file system to support IPC of type many-to-many. It resides in RAM, and supports regular files, directories, symbolic, and hard links. Each file on mumufs is associated with a data block of an arbitrary size. Read/write operations for a file correspond to read/write operations from/to the corresponding data block. Each successful write to a file operation replaces the previously stored data block. Each new read/write operation must start from the shift 0 from the beginning of a file. An operation is considered successful only if the whole data block is read or written. Each file can be opened for reading and writing simultaneously many times. Both blocking and non-blocking IO are supported. Mumufs supports select и poll operations.
