IOCTL_CDROM_READ_TOC IOCTL (ntddcdrm.h)
Returns the table of contents of the media. Obsolete, beginning with Windows Vista.
Major code
Input buffer
Input buffer.
Input buffer length
Parameters.DeviceIoControl.OutputBufferLength in the I/O stack location indicates the size, in bytes, of the buffer, which must be greater than or equal to sizeof(CDROM_TOC).Output buffer
The driver returns the CDROM_TOC data in the buffer at Irp->AssociatedIrp.SystemBuffer.
Output buffer length
Length of a CDROM_TOC.
Status block
The Information field is set to the number of bytes returned. The Status field is set to STATUS_SUCCESS, or possibly to STATUS_BUFFER_TOO_SMALL, STATUS_NO_MEDIA_IN_DEVICE, STATUS_DEVICE_NOT_READY, STATUS_IO_TIMEOUT, STATUS_IO_DEVICE_ERROR, STATUS_DEVICE_BUSY, or STATUS_VERIFY_REQUIRED.
Remarks
Beginning with Windows Vista, CDROM class drivers do not use this IOCTL. Prior to Windows Vista, this IOCTL was used for audio playback on older CD-ROM drives that supported direct audio output in hardware.
Client applications should use the Media Control Interface (MCI) API rather than issuing this IOCTL.
