Where To Find the Numeric Values For DeviceIoControl Codes RRS feed

  • Question

  • Hi

    Can someone tell me where I can find the numeric values for the DeviceIOControl codes?  In Particular I am looking for the numeric value of IOCTL_CDROM_DISC_INFO .

    I have spent hours searching for an answer but cannot find the information.  I am using this in a VB.NET application.

    Thanks on advance for any help.

  • Hi


    Thanks for your time and help.  I got the IOCTL_CDROM_DISC_INFO from the MSDN Library BlockDriver references.  I will get the information I need from the Read TOC command.
