sqlite3_close()

Closing A Database Connection

int sqlite3_close(sqlite3 *);

The sqlite3_close() routine is the destructor for thesqlite3object. Calls to sqlite3_close() return SQLITE_OK if thesqlite3object is successfully destroyed and all associated resources are deallocated.

Applications mustfinalizeallprepared statementsandcloseallBLOB handlesassociated with thesqlite3object prior to attempting to close the object. If sqlite3_close() is called on adatabase connectionthat still has outstandingprepared statementsorBLOB handles,then it returns SQLITE_BUSY.

Ifsqlite3_close()is invoked while a transaction is open,the transaction is automatically rolled back.

The C parameter tosqlite3_close(C)must be either a NULL pointer or ansqlite3object pointer obtained fromsqlite3_open(),sqlite3_open16(),orsqlite3_open_v2(),and not previously closed. Calling sqlite3_close() with a NULL pointer argument is a harmless no-op.
