Hi,
I’m trying to read 10 seconds of first audio track on CDDA,
using the following:
char *buff;
ULONG returned = 0;
RAW_READ_INFO rr_info;
ULONG NUM_BLOCKS_TO_READ = 75*10;
UINT CDDA_SECTOR_SIZE = 2352;
UINT LBA_OFFSET = 0;
rr_info.DiskOffset.QuadPart=LBA_OFFSET;
rr_info.SectorCount=NUM_BLOCKS_TO_READ;
rr_info.TrackMode=CDDA;
buff = (char*)malloc(CDDA_SECTOR_SIZE*NUM_BLOCKS_TO_READ);
if(!DeviceIoControl(devHandle,
IOCTL_CDROM_RAW_READ,
&rr_info,
sizeof(RAW_READ_INFO),
in_buff,
CDDA_SECTOR_SIZE*NUM_BLOCKS_TO_READ,
&returned,
NULL)) {
printf(“ERR[%d]\n”, GetLastError());
return 1;
}
This code is known to work under Win2K but doesn’t under NT,
DeviceIoControl failed with error code 1(INVALID_FUNCTION),
If you familiar with reading CDDA sectors under Win32
I would be glad to get any help.
v.
