| kSymlink | uint64_t{fuchsia_io::NodeProtocolKinds::kSymlink} | -- |
Identifies a single type of node protocol where required for protocol negotiation/resolution.
Defined at line 46 of file ../../src/storage/lib/vfs/cpp/vfs_types.h
enum class CreationMode : uint8_t| Name | Value | Comments |
|---|---|---|
| kNever | 0 |
Never create an object. Will return `ZX_ERR_NOT_FOUND` if there is no existing object. |
| kAllowExisting | 1 |
Create a new object if one doesn't already exist, otherwise open the existing object. |
| kAlways | 2 |
Always create an object. Will return `ZX_ERR_ALREADY_EXISTS` if one already exists. |
Indicates if and when a new object should be created when opening a node.

Functions
-
void * GetBlock (uint64_tblock_size,const void *data,uint64_tblkno)Access the "blkno"-th block within data.
"blkno = 0" corresponds to the first block within data.
Defined at line 22 of file ../../src/storage/lib/vfs/cpp/transaction/transaction_handler.h
-
zx_status_t MakeJournal (uint64_t journal_blocks, const WriteBlocksFn & WriteBlocks)Makes a journal that fits in |journal_blocks| by writing journal metadata using user supplied
write function, |WriteBlocks|. MakeJournal is called from host and from target while creating
different FSes. There isn't a common writer trait among the users to write to the backing data
store. WriteBlockFn is a work-around until then.
Defined at line 34 of file ../../src/storage/lib/vfs/cpp/journal/initializer.cc

bool IsValidName (std::string_view name)Defined at line 58 of file ../../src/storage/lib/vfs/cpp/vnode.h
-
zx_status_t ParseJournalEntries (const JournalSuperblock *info,storage::VmoBuffer *journal_buffer,std::vector<storage::BufferedOperation> *operations,uint64_t *out_sequence_number,uint64_t *out_start)Parses all entries within the journal, and returns the operations which must be replayed to
return the filesystem to a consistent state. Additionally returns the sequence number which
should be used to update the info block once replay has completed successfully.
This function is invoked by |ReplayJournal|. Refer to that function for the common case of
replaying a journal on boot.
Defined at line 123 of file ../../src/storage/lib/vfs/cpp/journal/replay.cc
-
zx::result<JournalSuperblock> ReplayJournal (fs::TransactionHandler *transaction_handler,storage::VmoidRegistry *registry,uint64_tjournal_start,uint64_tjournal_length,uint32_tblock_size)Replays the entries in the journal, first parsing them, and later writing them out to disk.
|journal_start| is the start of the journal area (includes info block).
|journal_length| is the length of the journal area (includes info block).
Returns the new |JournalSuperblock|, with an updated sequence number which should be used on
journal initialization.

fuchsia_io::OpenFlags RightsToOpenFlags (fuchsia_io::Rights rights)Defined at line 132 of file ../../src/storage/lib/vfs/cpp/vfs_types.cc
-
zx_status_t OpenVnode (fbl::RefPtr<Vnode> * vnode)Opens a vnode by reference.
The |vnode| reference is updated in-place if redirection occurs.
