NtQueryInformationTransaction function (wdm.h)
The ZwQueryInformationTransaction routine retrieves information about a specified transaction.
Syntax
__kernel_entry NTSYSCALLAPI NTSTATUS NtQueryInformationTransaction(
[in] HANDLE TransactionHandle,
[in] TRANSACTION_INFORMATION_CLASS TransactionInformationClass,
[out] PVOID TransactionInformation,
[in] ULONG TransactionInformationLength,
[out, optional] PULONG ReturnLength
);
Parameters
[in] TransactionHandle
A handle to a transaction object that was obtained by a previous call to ZwCreateTransaction or ZwOpenTransaction. The handle must have TRANSACTION_QUERY_INFORMATION access to the object.
[in] TransactionInformationClass
A TRANSACTION_INFORMATION_CLASS-typed value that specifies the information to obtain. The value must be one of the following values:
- TransactionBasicInformation
- TransactionPropertiesInformation
- TransactionEnlistmentInformation
[out] TransactionInformation
A pointer to a caller-allocated buffer that receives the information that the TransactionInformationClass parameter specifies. The buffer's structure type must be TRANSACTION_BASIC_INFORMATION, TRANSACTION_PROPERTIES_INFORMATION, or TRANSACTION_ENLISTMENTS_INFORMATION.
[in] TransactionInformationLength
The length, in bytes, of the buffer that the TransactionInformation parameter points to, including the length of any additional array elements that the caller has allocated to receive information.
[out, optional] ReturnLength
A pointer to a caller-allocated variable that receives the length, in bytes, of the information that KTM writes to the TransactionInformation buffer. This parameter is optional and can be NULL.
Return value
ZwQueryInformationTransaction returns STATUS_SUCCESS if the operation succeeds. Otherwise, this routine might return one of the following values:
Return code | Description |
---|---|
|
The TransactionInformationClass parameter's value is invalid. |
|
The length of the buffer that is specified by the TransactionInformationLength parameter is incorrect. |
|
The handle that the TransactionHandle parameter specifies is not a handle to a transaction object. |
|
An object handle is invalid. |
|
The caller does not have appropriate access to the transaction object. |
|
The buffer that the TransactionInformation parameter specifies is too small. |
The routine might return other NTSTATUS values.
Remarks
For more information about how to use ZwQueryInformationTransaction, see Creating a Transactional Client.
NtQueryInformationTransaction and ZwQueryInformationTransaction 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.
