Luna::VFS::DriverDesc

Describes one virtual file system (VFS) driver.

struct Luna::VFS::DriverDesc

One VFS driver describes functions to operate files on a certain kind of media. For example, one ZIP driver may provide functions to read files from one ZIP archive, and the file devices created from the driver represents one real ZIP file opened for reading.

Member objects
