Start acquiring locks by passing the appropriate lock mode to the Lock method inherited by CTSession, CTDatabase, CTTable, and CTRecord from CTBase.
// start locking
ARecord.Lock(LOCK_MODE.WRITE_BLOCK_LOCK);
After a successful call to Lock, the c-treeDB .NET API locks all records as they are read using the lock mode passed to Lock. Suspend record locking temporarily by calling the Lock function with the mode LOCK_MODE.SUSPEND_LOCK. Suspending locks does not release any locks, but while locks are suspended, no record reads are automatically locked.
// suspend locking
ARecord.Lock(LOCK_MODE.SUSPEND_LOCK);
Suspended locking can be resumed by calling Lock with a restore lock mode: LOCK_MODE.RESTORE_READ_LOCK, LOCK_MODE.RESTORE_READ_BLOCK_LOCK, LOCK_MODE.RESTORE_WRITE_LOCK, or LOCK_MODE.RESTORE_WRITE_BLOCK_LOCK.
// resume locking
try
{
ARecord.Lock(LOCK_MODE.RESTORE_WRITE_BLOCK_LOCK);
}
catch (CTException err)
{
Console.Write("Resume lock failed with error {0}\n", err.GetErrorCode());
}
