LSA_FREE_CLIENT_BUFFER callback function (ntsecpkg.h)
Frees a client buffer previously allocated with the AllocateClientBuffer function.
Syntax
LSA_FREE_CLIENT_BUFFER LsaFreeClientBuffer;
NTSTATUS LsaFreeClientBuffer(
[in] PLSA_CLIENT_REQUEST ClientRequest,
[in] PVOID ClientBaseAddress
)
{...}
Parameters
[in] ClientRequest
Pointer to an opaque LSA_CLIENT_REQUEST data type containing information about the LSA client's request.
[in] ClientBaseAddress
Optional. Pointer to the buffer to be freed. This address is the virtual address of the buffer within the client process, not in the current process. If NULL is passed, no memory is freed. This allows the client to pass in a value returned to it by the LSA without knowing whether the LSA actually allocated a buffer.
Return value
If the function succeeds, the return value is STATUS_SUCCESS.
If the function fails, the return value is an NTSTATUS code. For more information, see LSA Policy Function Return Values.
The LsaNtStatusToWinError function converts an NTSTATUS code to a Windows error code.
Remarks
Because this function frees pages in the client's process, it must be called with great care. Calling this function with an address that is not valid can cause the client process to crash.
