Data Types
The journalling layer uses typedefs to 'hide' the concrete definitions
of the structures used. As a client of the JBD layer you can
just rely on the using the pointer as a magic cookie of some sort.
Obviously the hiding is not enforced as this is 'C'.
- Table of Contents
- typedef handle_t -- The handle_t type represents a single atomic update being performed by some process.
- typedef journal_t -- The journal_t maintains all of the journaling state information for a single filesystem.
- struct journal_s -- The journal_s type is the concrete type associated with journal_t.
