ZwRecoverEnlistment function (wdm.h)

The ZwRecoverEnlistment routine initiates a recovery operation for the transaction that is associated with a specified enlistment.

Syntax

NTSYSCALLAPI NTSTATUS ZwRecoverEnlistment(
  [in]           HANDLE EnlistmentHandle,
  [in, optional] PVOID  EnlistmentKey
);

Parameters

[in] EnlistmentHandle

A handle to an enlistment object that was obtained by a previous call to ZwCreateEnlistment or ZwOpenEnlistment. The handle must have ENLISTMENT_RECOVER access to the object.

[in, optional] EnlistmentKey

A pointer to the enlistment key value that the resource manager previously specified as the EnlistmentKey parameter to ZwCreateEnlistment. This parameter is optional and can be NULL if the resource manager did not provide an enlistment key when it called ZwCreateEnlistment.

Return value

ZwRecoverEnlistment returns STATUS_SUCCESS if the operation succeeds. Otherwise, this routine might return one of the following values:

Return code	Description
STATUS_OBJECT_TYPE_MISMATCH	The specified handle is not a handle to an enlistment object.
STATUS_INVALID_HANDLE	The object handle is invalid.
STATUS_TRANSACTION_REQUEST_NOT_VALID	The transaction or its enlistment is not in the correct state.
STATUS_PENDING	KTM has added a commit, rollback, or in-doubt notification to the resource manager's notification queue, and the resource manager is not using a ResourceManagerNotification callback routine.
STATUS_ACCESS_DENIED	The caller does not have appropriate access to the enlistment object.

 

The routine might return other NTSTATUS values.

Remarks

After a resource manager calls ZwRecoverEnlistment, KTM delivers either a TRANSACTION_NOTIFY_COMMIT, TRANSACTION_NOTIFY_ROLLBACK, or TRANSACTION_NOTIFY_INDOUBT notification for the enlistment. Therefore, unless the resource manager is using a ResourceManagerNotification callback routine, it must immediately call ZwGetNotificationResourceManager if ZwRecoverEnlistment returns STATUS_SUCCESS or STATUS_PENDING.

NtRecoverEnlistment and ZwRecoverEnlistment are two versions of the same Windows Native System Services routine.

For calls from kernel-mode drivers, the NtXxx and ZwXxx versions of a Windows Native System Services routine can behave differently in the way that they handle and interpret input parameters. For more information about the relationship between the NtXxx and ZwXxx versions of a routine, see Using Nt and Zw Versions of the Native System Services Routines.
