Berkeley DB: DBcursor->c_close
DBcursor->c_close
|
 
|
#include <db.h>
int
DBcursor->c_close(DBC *cursor);
Description
The DBcursor->c_close function discards the cursor.
It is possible for the DBcursor->c_close function to return
DB_LOCK_DEADLOCK, signaling that any enclosing transaction should
be aborted. If the application is already intending to abort the
transaction, this error should be ignored, and the application should
proceed.
After DBcursor->c_close has been called, regardless of its return, the
cursor handle may not be used again.
The DBcursor->c_close function returns a non-zero error value on failure and 0 on success.
Errors
The DBcursor->c_close function may fail and return a non-zero error for the following conditions:
- DB_LOCK_DEADLOCK
- The operation was selected to resolve a deadlock.
- EINVAL
- An invalid flag value or parameter was specified.
The cursor was previously closed.
The DBcursor->c_close function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
If a catastrophic error has occurred, the DBcursor->c_close function may fail and return
DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail
in the same way.
