struct sqlite3_file

An sqlite3_file object represents an open file in the OS interface layer. Individual OS interface implementations will want to subclass this object by appending additional fields for their own use. The pMethods entry is a pointer to an sqlite3_io_methods object ... 

struct sqlite3_blob

An instance of this object represents an open BLOB on which incremental BLOB I/O can be performed. Objects of this type are created by sqlite3_blob_open() and destroyed by sqlite3_blob_close(). The sqlite3_blob_read() and sqlite3_blob_write() interfaces can be used to read ... 

sqlite3_blob_bytes()

Returns the size in bytes of the BLOB accessible via the successfully opened BLOB handle in its only argument. The incremental blob I/O routines can only read or overwriting existing blob content; they cannot change the size of a ... 

sqlite3_open_v2(), SQLITE_OPEN_READONLY, SQLITE_OPEN_READWRITE, SQLITE_OPEN_CREATE, SQLITE_OPEN_DELETEONCLOSE, SQLITE_OPEN_EXCLUSIVE ... 

 ... Note in particular that passing the SQLITE_OPEN_EXCLUSIVE flag into sqlite3_open_v2() does *not* cause the underlying database file to be opened using O_EXCL. Passing SQLITE_OPEN_EXCLUSIVE into sqlite3_open_v2() has historically be a no-op and might become an error in future versions ... 

sqlite3_blob_open()

This interfaces opens a handle to the BLOB located in row iRow, column zColumn, table zTable in database zDb; in other words, the same BLOB that would be selected by: SELECT zColumn FROM zDb.zTable WHERE rowid = iRow; Parameter zDb ... 

sqlite3_open(), sqlite3_open16()

These routines open an SQLite database file as specified by the filename argument. The filename argument is interpreted as UTF-8 for sqlite3_open() and sqlite3_open_v2() and as UTF-16 in the native byte order for sqlite3_open16(). A database connection handle ... 

 ... In other words, instead of passing the name of a real disk file into one of the sqlite3_open(), sqlite3_open16(), or sqlite3_open_v2() functions, pass in the string ":memory:". For example: rc = sqlite3_open(":memory:", &db); When this is done, no disk ... 

sqlite3_snapshot_get()

 ... If there is not already a read-transaction open on schema S when this function is called, one is opened automatically. If a read-transaction is opened by this function, then it is guaranteed that the returned snapshot object may ... 

3.3. The "openclose" Callback The "openclose" parameter allows the user to specify the name of a application-defined SQL function that will be invoked just before swarmvtab opens a database, and again just after it closes one. The first argument passed to the open ... 

sqlite3_blob_close()

This function closes an open BLOB handle. The BLOB handle is closed unconditionally. Even if this routine returns an error code, the handle is still closed. If the blob handle being closed was opened for read-write access, and if ...
