PVOID
MIDL_user_allocate(
    IN size_t NumBytes
    )
/*++

Routine Description:

    Allocates storage for RPC transactions. The RPC stubs will either call
    MIDL_user_allocate when it needs to un-marshall data into a buffer
    that the user must free.  RPC servers will use MIDL_user_allocate to
    allocate storage that the RPC server stub will free after marshalling
    the data.

Arguments:

    NumBytes - the number of bytes to allocate.

Return Value:

    None.

VOID
MIDL_user_free(
    IN void * MemPointer
    )
/*++

Routine Description:

    Frees storage used in RPC transactions. The RPC client can call this
    function to free buffer space that was allocated by the RPC client
    stub when un-marshalling data that is to be returned to the client.
    The Client calls MIDL_user_free when it is finished with the data and
    desires to free up the storage.
    The RPC server stub calls MIDL_user_free when it has completed
    marshalling server data that is to be passed back to the client.

Arguments:

    MemPointer - pointer to the memory block that is to be released.

Return Value:

    None.
