Thread: How to get device serial no/ID in C?

Hi,
Can anyone help me to get device serial no/ID in C, such as the serial no of HDD:IDE/SCSI, Main Board, Floppy.

Category :Windows API

Question:
How can I get volume information, such as the serial number,
from my drivers?

Answer:
procedure TForm1.Button1Click(Sender: TObject);
var
VolumeName,
FileSystemName : array [0..MAX_PATH-1] of Char;
VolumeSerialNo : DWord;
MaxComponentLength,
FileSystemFlags : Integer;
begin
GetVolumeInformation('C:\',VolumeName,MAX_PATH,@Vo lumeSerialNo,
MaxComponentLength,FileSystemFlags,
FileSystemName,MAX_PATH);
Memo1.Lines.Add('VName = '+VolumeName);
Memo1.Lines.Add('SerialNo = $'+IntToHex(VolumeSerialNo,8));
Memo1.Lines.Add('CompLen = '+IntToStr(MaxComponentLength));
Memo1.Lines.Add('Flags = $'+IntToHex(FileSystemFlags,4));
Memo1.Lines.Add('FSName = '+FileSystemName);
end;

Can anyone translate it into C?

GetVolumeInformation In

Turbo C++
Version 3.0

No function found.....

hahaha, Yeah.. fossil compiler.
What is the header file for that function ?
Do you know the library..

Anyway.. I will check your links.

Code:

int GetIdeInfo (int Drive, unsigned int *DInfo)
{
    volatile unsigned int retry;
    int wordno;

    /* Wait until controller is not busy */
    retry = UINT_MAX;
    while ((inp(0x1F7) != 0x50) && --retry);
    if (!retry) return 1;

    /* Get drive information */
    outp(0x1F6, Drive ? 0xB0:0xA0);
    outp(0x1F7, 0xEC);

    /* Wait until data is available */
    retry = UINT_MAX;

while ((inp(0x1F7) != 0x58) && --retry);
    if (!retry) return 1;

    /* Read the drive information */
    for (wordno=0; wordno<256; wordno++)
	DInfo[wordno] = inpw(0x1F0);

    /* Return succesful */
    return  (0);
}


const char *ToText (const unsigned int *Data, int Start, int End)
{
    static char Dest[512];
    int Ctr1, Ctr2;
    int i;

    for (Ctr1 = Start, Ctr2 = 0; Ctr1 <= End; Ctr1++, Ctr2 += 2)
    {
		Dest[Ctr2+0] = (char) (Data[Ctr1] >> 8);
		Dest[Ctr2+1] = (char) (Data[Ctr1] & 255);
    }
    Dest[Ctr2] = '\0';

    for(i=strlen(Dest)-1;i>=0;i--)
		if(Dest[i]==' ')
			Dest[i]=0;
		else
			break;

     return (Dest);
}

Any idea on the functions? Specially for Salem.
