View the official Windows Driver Kit DDI referenceThe ZwReadOnlyEnlistment routine sets a specified enlistment to be read-only.
EnlistmentHandle [in]A handle to an enlistment object that was obtained by a previous call to ZwCreateEnlistment or ZwOpenEnlistment. The handle must have ENLISTMENT_SUBORDINATE_RIGHTS access to the object.
TmVirtualClock [in, optional]A pointer to a virtual clock value. This parameter is optional and can be NULL.
ZwReadOnlyEnlistment 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_NOT_REQUESTED | The transaction or its enlistment is not in the correct state. For example, an enlistment cannot be read-only if the ENLISTMENT_SUPERIOR flag was specified to ZwCreateEnlistment. |
| STATUS_ACCESS_DENIED | The caller does not have appropriate access to the enlistment object. |
The routine might return other NTSTATUS values.
Your component cannot call ZwReadOnlyEnlistment for a superior enlistment.

NtReadOnlyEnlistment and ZwReadOnlyEnlistment are two versions of the same Windows Native System Services routine.
For calls from kernel-mode drivers, the Nt*Xxx* and Zw*Xxx* 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 Nt*Xxx* and Zw*Xxx* versions of a routine, see Using Nt and Zw Versions of the Native System Services Routines.
