Par2: 32 bit Disk serial number 1998-12-20 -- Arnor Baldvinsson >The 16 Bit versions of getting the disk information (int86x) returns the

For this you can use the GetVolumeInformation api call - it does a lot
more than just get the volume label. Here are some code snippets:
"After global includes"
FORMAT_MESSAGE_ALLOCATE_BUFFER EQUATE(00000100H)
FORMAT_MESSAGE_ARGUMENT_ARRAY EQUATE(00002000H)
FORMAT_MESSAGE_FROM_HMODULE EQUATE(00000800H)
FORMAT_MESSAGE_FROM_STRING EQUATE(00000400H)
FORMAT_MESSAGE_FROM_SYSTEM EQUATE(00001000H)
FORMAT_MESSAGE_IGNORE_INSERTS EQUATE(00000200H)
FORMAT_MESSAGE_MAX_WIDTH_MASK EQUATE(000000FFH)
va_list EQUATE(LONG) !*LPCSTR
"Inside the global Map"
COMPILE('***',_WIDTH32_)
MODULE('WIN32.LIB')
GetDriveType(*LPCSTR),UNSIGNED,PASCAL,RAW,NAME('GetDriveTypeA')
CopyFileA(*LPCSTR,*LPCSTR,BOOL),BOOL,PASCAL,RAW
GetVolumeInformationA(*LPCSTR,*LPSTR,DWORD,*DWORD,*DWORD,*DWORD,|
*LPSTR ,DWORD),BOOL,PASCAL,RAW
GetLastError(),DWORD,PASCAL
FormatMessageA(DWORD,LPCVOID,DWORD,DWORD,*LPSTR,DWORD,va_list),DWORD,PASCAL,RAW

Some code:
GetVolumeID ROUTINE
LOC:RootPathName = CHR(64+LOC:Entries) & ':\'
LOC:VolNameSize = SIZE(LOC:VolNameBuffer)
LOC:FileSystemSize = SIZE(LOC:FileSystem)
X# = GetVolumeInformationA(LOC:RootPathName, |
LOC:VolNameBuffer, |
LOC:VolNameSize, |
LOC:VolSerialNr, |
LOC:MaxFCL, |
LOC:MaxFCF, |
LOC:FileSystem, |
LOC:FileSystemSize)
LOC:VolNameBuffer = LOWER(LOC:VolNameBuffer)
Variables:
LOC:RootPathName CSTRING(255)
LOC:VolNameBuffer CSTRING(255)
LOC:VolNameSize ULONG
LOC:VolSerialNr ULONG
LOC:MaxFCL ULONG
LOC:MaxFCF ULONG
LOC:FileSystem CSTRING(255)
LOC:FileSystemSize LONG
