LSA_CLIENT_CALLBACK callback function (ntsecpkg.h)
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
LSA_CLIENT_CALLBACK LsaClientCallback;
NTSTATUS LsaClientCallback(
[in] PCHAR Callback,
[in] ULONG_PTR Argument1,
[in] ULONG_PTR Argument2,
[in] PSecBuffer Input,
[out] PSecBuffer Output
)
{...}
Parameters
[in] Callback
A pointer to the name of the function to invoke. For more information, see ClientCallback_Function.
[in] Argument1
A pointer to the first argument to pass to the callback function.
[in] Argument2
A pointer to the second argument to pass to the callback function.
[in] Input
A pointer to a SecBuffer structure that contains information to pass to the callback function.
[out] Output
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.
