u_int8_t *conflicts, int nmodes);
Set the locking conflicts matrix.
The conflicts argument
is an nmodes by nmodes array.
A non-0 value for the array element indicates that requested_mode and
The not-granted mode must be represented by 0.
If DB_ENV->set_lk_conflicts is never called, a standard conflicts
array is used; see Standard Lock
Modes for more information.
The DB_ENV->set_lk_conflicts method configures a database environment, not only operations
performed using the specified DB_ENV handle.
The DB_ENV->set_lk_conflicts interface may not be called after the DB_ENV->open
interface is called.
If the database environment already exists when
DB_ENV->open is called, the information specified to DB_ENV->set_lk_conflicts
will be ignored.
The DB_ENV->set_lk_conflicts method returns a non-zero error value on failure and 0 on success.
The DB_ENV->set_lk_conflicts method may fail and return a non-zero error for the following conditions:
- An invalid flag value or parameter was specified.
Called after DB_ENV->open was called.
- No memory was available to copy the conflicts array.
The DB_ENV->set_lk_conflicts method 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 DB_ENV->set_lk_conflicts method may fail and
in which case all subsequent Berkeley DB calls will fail in the same way.
