sqlite3_blob_write()

This function is used to write data into an open BLOB handle from a caller-supplied buffer. N bytes of data are copied from the buffer Z into the open BLOB, starting at offset iOffset. On success, sqlite3_blob_write() returns SQLITE_OK ... 

struct sqlite3_snapshot

 ... In WAL mode, multiple database connections that are open on the same database file can each be reading a different historical version of the database file. When a database connection begins a read transaction, that connection sees an unchanging copy ... 

sqlite3_blob_read()

This function is used to read data from an open BLOB handle into a caller-supplied buffer. N bytes of data are copied into buffer Z from the open BLOB, starting at offset iOffset. If offset iOffset is less than ... 

sqlite3_blob_reopen()

 ... The database, table and column on which the blob handle is open remain the same. Moving an existing BLOB handle to a new row is faster than closing the existing handle and opening a new one. The new row must ... 

sqlite3_auto_extension(), struct sqlite3_api_routines

 ... If any xEntryPoint() returns an error, the sqlite3_open(), sqlite3_open16(), or sqlite3_open_v2() call that provoked the xEntryPoint() will fail. Calling sqlite3_auto_extension(X) with an entry point X that is already on the list of automatic extensions is a harmless no-op ... 

sqlite3_syscall_ptr(), struct sqlite3_vfs

 ... Or if sqlite3_open() or sqlite3_open16() is used, then flags includes at least SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE. If xOpen() opens a file read-only then it sets *pOutFlags to include SQLITE_OPEN_READONLY. Other bits in *pOutFlags may be set. SQLite will also add one ... 

 ... SQLite is open-source but it is not open-contribution. All the code in SQLite is written by a small team of experts. The project does not accept "pull requests" or patches from anonymous passers-by on the internet. The ... 

2.6. Carrying an open database connection across a fork() Do not open an SQLite database connection, then fork(), then try to use that database connection in the child process. All kinds of locking problems will result and you can easily end up with a corrupt database. SQLite is not ... 

sqlite3_initialize(), sqlite3_shutdown(), sqlite3_os_init(), sqlite3_os_end()

 ... For example, sqlite3_open() calls sqlite3_initialize() so the SQLite library will be automatically initialized when sqlite3_open() is called if it has not be initialized already. However, if SQLite is compiled with the SQLITE_OMIT_AUTOINIT compile-time option, then the automatic calls to ... 

4. VFS Implementations  ... The sqlite3_file object represents an open file. The xOpen method of sqlite3_vfs constructs an sqlite3_file object when the file is opened. The sqlite3_file keeps track of the state of the file while it is opened. The sqlite3_io_methods object holds the ...
