    C++ Syntax

    I am having trouble with some existing C++ that I have been asked to modify. Can someone please explain the following code to me please?

    Code:
    extern "C" void SpiPutword( Uint16 w )
    {
        Lcd().ProcessDataWord( w );
    }
    I don't recall coming across funtion1().funtion2() before...

    The above code was taken from a VS2005 C++ MFC project. Basically it's suppose to be a test harness (PC emulator) for a touchscreen wall controller (ie., air conditioner wall controller).

    Any suggestions or advice would be much appreciated.

    Thanks.

    Lcd() returns an object that contains function ProcessDataWord().

    You might be more familiar with:
    Code:
    x = Lcd();
    x.ProcessDataWord( w );
    The code you read merely eliminated the variable x by chaining the function calls.
