typedef struct sqlite3_blob sqlite3_blob;
这个对象的实例表示一个打开的BLOB,在这个对象上可以执行增量 BLOB I/O。这个对象使用sqlite3_blob_open()创建,使用sqlite3_blob_close()销毁。可以使用sqlite3_blob_read() 和 sqlite3_blob_write()接口来读写BLOB的一小段。sqlite3_blob_bytes()接口返回BLOB的字节大小。
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.
