ZwCurrentThread

  • Article

Defined in: Wdm.h

The ZwCurrentThread macro returns a handle to the current thread.

Return value

HANDLE

ZwCurrentThread returns a special handle value that represents the current thread.

The returned value is not a true handle, but it is a special value that always represents the current thread.

NtCurrentThread and ZwCurrentThread are two versions of the same Windows Native System Services routine. The NtCurrentThread routine in the Windows kernel is not directly accessible to kernel-mode drivers. However, kernel-mode drivers can access this routine indirectly by calling the ZwCurrentThread 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.
