    Help with very easy program

    Hi guys,

    I'm a first time visitor here so hello to all.

    Could any of you post some C Code for a program to make a buzzer sound for 2 seconds please?

    Basically, it hasnt got to interface any hardware directly - just a theoretical program for a beginner in C Programming project

    PS - the adress for the speaker is 0x378 H and the Output of it is 0x379 (0x is Hexadecimal)

    Thanks a lot

    sry about that - i wasnt aware of that rule.

    This is what I have so far


    Code:
    #include<conio.h>
    #include<stdio.h>
    #include<window.h>
    void main()
    {
    _Inp(0x378 , 0xff);
    	Sleep(2000);
    	_Outp(0x379, 0x00);
    }

    in MS-Windows normal programs cannot access ports directly. you might try PlaySound()

    Hello,

    yes I know - this is just a theoretical program - its not actually going to be used - think of it as kinda for a school project

    1) Don't void main.
    2) I could be wrong, but aren't the functions you're trying to use _inp(unsigned short) and _outp(unsigned short, int)?
    If I did your homework for you, then you might pass your class without learning how to write a program like this. Then you might graduate and get your degree without learning how to write a program like this. You might become a professional programmer without knowing how to write a program like this. Someday you might work on a project with me without knowing how to write a program like this. Then I would have to do you serious bodily harm. - Jack Klein

    Try google for the prototypes of functions like inp. You probably won't get anyone here to write your code for you.

    BTW, it's <windows.h>, not <window.h>.

    There is no such thing as a "theoritical program". Programs are not written by theory alone. I could just type in a bunch of shi$ too, but that doesn't make it a computer program.

    MS-DOS 6.X and Win95 are the only two operating systems that can use the _inp() and _output() functions. Other versions of MS-Windows will forbid a program from using them.

    Windows 98 works, too. And I imagine earlier version of DOS (like 3) would allow it as well.

    [edit]
    And it's _outp(), not _output() (I think).
