This function is documented in Windows Driver Kit here and here.

Windows Driver Kit DDI reference (nf-wdm-ntqueryinformationresourcemanager)

NtQueryInformationResourceManager function

Description

The ZwQueryInformationResourceManager routine retrieves information about a specified resource manager object.

Parameters

ResourceManagerHandle [in]

A handle to a resource manager object that was obtained by a previous call to ZwCreateResourceManager or ZwOpenResourceManager. The handle must have RESOURCEMANAGER_QUERY_INFORMATION access to the object.

ResourceManagerInformationClass [in]

A RESOURCEMANAGER_INFORMATION_CLASS-typed value that specifies the information to retrieve. This value must be ResourceManagerBasicInformation.

ResourceManagerInformation [out]

A pointer to a caller-allocated RESOURCEMANAGER_BASIC_INFORMATION structure that receives information from ZwQueryInformationResourceManager.

ResourceManagerInformationLength [in]

The length, in bytes, of the buffer that the ResourceManagerInformation parameter points to.

ReturnLength [out, optional]

A pointer to a caller-allocated variable that receives the length, in bytes, of the information that KTM writes to the ResourceManagerInformation buffer. This parameter is optional and can be NULL.

Return value

ZwQueryInformationResourceManager 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 a resource manager object.
STATUS_INVALID_HANDLE An object handle is invalid.
STATUS_INVALID_INFO_CLASS The ResourceManagerInformationClass parameter's value is invalid.
STATUS_BUFFER_TOO_SMALL The buffer size that the ResourceManagerInformationLength parameter specifies is smaller than the RESOURCEMANAGER_BASIC_INFORMATION structure.
STATUS_BUFFER_OVERFLOW The buffer size that the ResourceManagerInformationLength parameter specifies is too small to receive all the variable-length information that is available.
STATUS_ACCESS_DENIED The caller does not have appropriate access to the resource manager object.

The routine might return other NTSTATUS values.

Remarks

For more information about the ZwQueryInformationResourceManager routine, see Creating a Resource Manager.

NtQueryInformationResourceManager and ZwQueryInformationResourceManager 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.
