Article
10/21/2021

The CreateThread callback method is called by the engine when a create-threaddebugging event occurs in the target.

Syntax

HRESULT CreateThread(
  [in] ULONG64 Handle,
  [in] ULONG64 DataOffset,
  [in] ULONG64 StartOffset
);

Parameters

[in] Handle

Specifies the handle for the thread whose creation caused the event. If this information is not available, Handle will be NULL.

[in] DataOffset

Specifies a block of data that the operating system maintains for this thread. The actual data in the block is operating system-specific. If the operating system does not have such a block, DataOffset will be NULL.

[in] StartOffset

Specifies the starting location in the target's virtual address space of the thread. If this information is not available, StartOffset will be NULL.

Return value

This method returns a DEBUG_STATUS_XXX value, which indicates how the execution of the target should proceed after the engine processes this event. For details on how the engine treats this value, see Monitoring Events.

Remarks

This method is only called by the engine if the DEBUG_EVENT_CREATE_THREAD flag is set in the mask returned by IDebugEventCallbacks::GetInterestMask.

For more information about handling events, see Monitoring Events. For information about threads, see Threads and Processes.
