ClientCallback function
The ClientCallback function allows a Local Security Authority (LSA)-mode security package to call back to its user-mode package and invoke a function in its DLL there.
Syntax
NTSTATUS ClientCallback( _In_ PCHAR Callback, _In_ ULONG_PTR Argument1, _In_ ULONG_PTR Argument2, _In_ PSecBuffer Input, _Out_ PSecBuffer Output );
Parameters
- Callback [in]
-
A pointer to the name of the function to invoke. For more information, see ClientCallback_Function.
- Argument1 [in]
-
A pointer to the first argument to pass to the callback function.
- Argument2 [in]
-
A pointer to the second argument to pass to the callback function.
- Input [in]
-
A pointer to a SecBuffer structure that contains information to pass to the callback function.
- Output [out]
-
A pointer to a SecBuffer structure that receives information passed from the callback function.
Return value
If the function succeeds, the function returns STATUS_SUCCESS.
If the function fails, it returns an NTSTATUS code that indicates the reason it failed.
Remarks
A pointer to the ClientCallback function is available in the LSA_SECPKG_FUNCTION_TABLE structure received by the SpInitialize function.
The user-mode security package must use the RegisterCallback function to register the function to be called.
