A Handle To An Open BLOB

typedef struct sqlite3_blob 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 or write small subsections of the BLOB. The sqlite3_blob_bytes() interface returns the size of the BLOB in bytes.

1 Constructor: sqlite3_blob_open()

1 Destructor: sqlite3_blob_close()

4 Methods: sqlite3_blob_bytes(), sqlite3_blob_read(), sqlite3_blob_reopen(), sqlite3_blob_write()
