CreateThread function

The CreateThread function is a wrapper for the Windows CreateThread function that should be used by the Local Security Authority (LSA). It creates a thread that the LSA can track, attaches debugging information to threads it starts, and provides special exception handling to protect the LSA process.

Syntax


HANDLE CreateThread(
  _In_   SEC_ATTRS SecurityAttributes,
  _In_   ULONG StackSize,
  _In_   SEC_THREAD_START StartFunction,
  _In_   PVOID ThreadParameter,
  _In_   ULONG CreationFlags,
  _Out_  PULONG ThreadId
);

Parameters

SecurityAttributes [in]

Pointer to a SEC_ATTRS structure that determines whether the returned handle can be inherited by child processes.

StackSize [in]

Specifies the initial commit size of the stack, in bytes.

StartFunction [in]

Pointer to the application-defined function of type SEC_THREAD_START to be executed by the thread.

ThreadParameter [in]

Pointer to a single parameter value passed to the thread.

CreationFlags [in]

Specifies flags that control the creation of the thread.

ThreadId [out]

Pointer to a variable that receives the thread identifier.

Return value

If the function succeeds, the return value is a handle to the new thread. When you have finished using the handle, close it by calling the CloseHandle function.

If the function fails, the return value is NULL. To get extended error information, call GetLastError.

Remarks

A pointer to the CreateThread function is available in the LSA_SECPKG_FUNCTION_TABLE structure received by the SpInitialize function.

For more information, see the Windows CreateThread function.
