Basic Music In C

Well, I believe you'll either have to use DirectSound (or some other library), or program the soundcard registers directly through DOS interrupts or something.

Its not known to be a very simple thing to do.. why do you think most games used 3rd party libraries in the DOS days? And if you count DirectSound/Music, they still use 3rd party stuff.

...I could be wrong though.

Well, you could always check out the Allegro source code...

Well Now,

Is there way I can link to a wav or midi file like some simple games seem to do.

Mega Moh Mine!!


The Yipsilon Home Page (Under Construction)

look up PlaySound to play a wav file in a win32 program (pretty sure it works in console apps)

Hey, does anyone know how to get the good ol'' mighty pc speaker playing from C? God, I miss those times...

Here is what you need to do simple, standard MCI midi playing in windows, as cut/pasted out of my code.


void CGameBoard:layMusic()
{
UINT deviceID;
DWORD dwReturn;
MCI_OPEN_PARMS openParms;
MCI_PLAY_PARMS playParms;
char buff[100];

openParms.lpstrDeviceType = "sequencer";
openParms.lpstrElementName = "pegmusic.mid";
if (dwReturn = mciSendCommand(NULL, MCI_OPEN, MCI_OPEN_TYPE|MCI_OPEN_ELEMENT|MCI_WAIT,
(DWORD)(LPVOID)&openParms))
{
mciGetErrorString(dwReturn, buff, sizeof(buff));
MessageBox(buff, "ERROR", MB_OK|MB_ICONEXCLAMATION);
return;
}
deviceID = openParms.wDeviceID;
playParms.dwCallback = (DWORD)m_hWnd;
if (dwReturn = mciSendCommand(deviceID, MCI_PLAY, MCI_NOTIFY, (DWORD)(LPVOID)&playParms))
return;
m_deviceID = deviceID;
m_playParms = playParms;
}

LONG CGameBoard::OnMciNotify(UINT wFlags, LONG lDevId)
{
MCI_PLAY_PARMS playParms;
playParms.dwFrom = 0;
switch(wFlags) {
case MCI_NOTIFY_SUCCESSFUL:
playParms.dwCallback = (DWORD)m_hWnd;
mciSendCommand(lDevId, MCI_PLAY, MCI_NOTIFY|MCI_FROM, (DWORD)(LPVOID)&playParms);
break;
case MCI_NOTIFY_FAILURE:
// m_wndStatus.SetWindowText(_T("Playback interrupted!"));
break;
case MCI_NOTIFY_SUPERSEDED:
// m_wndStatus.SetWindowText(_T("Playback stopped!"));
break;
}
return 0L;
}

void CGameBoard::SetMusicOff(BOOL off)
{
if (m_bMusicFlag)
{
if (off)
mciSendCommand(MCI_ALL_DEVICE_ID, MCI_CLOSE, NULL, NULL);
}
else
{
if (!off)
PlayMusic();
}

m_bMusicFlag = !off;
}


Note that this means you have to process the
MM_MCINOTIFY
in your message handlers, so that the song will restart when it finishes.

Tell me if you have problems.
