    Question Macro Error for Driver Development

    Hey Everyone,

    I've been doing some system stuff and I went to compile my driver today using the WDK Checked Build Environment. I keep getting a bunch of errors but I think they're all being caused by one:

    Code:
    // ctrlcode.h
    #define FILE_DEVICE_RK 0x00008001
    #define IOCTL_TEST_CMD\
    CTL_CODE(FILE_DEVICE_RK,0x801,METHOD_BUFFERED,FILE_READ_DATA|FILE_WRITE_DATA)
    Error C2010: '0' : unexpected in macro formal parameter list
    Error C2010: '|' : unexpected in macro formal parameter list
    Error C2010: 'F' : unexpected in macro formal parameter list

    I think, like I said, the other errors I'm getting other than the ones above are because it's not compiling the above include file correctly.

    It's giving me a problem over the 0x801 hex value and the Or ( | ) between the File Read/Writes.

    Any help would be greatly appreciated! I haven't worked in C for years and now I'm getting back to it and am clearly a bit rusty.

    Thanks!

    I think you need a space after IOCTL_TEST_CMD and before the backslash.
