Build

CtlCode

A ioctl code converter. Converts a given ioctl code into its parts (DeviceType, Function, Method, Access), or the parts into an ioctl code.

version

1.0.2
Last changed: 30.04.2024

build

$devcmd> build /ctl

examples

# convert ioctl code into parts
$ CtlCode.exe 0x10000
ioctl: 0x10000

deviceType: 0x1 (FILE_DEVICE_BEEP)
function: 0x0
method: 0x0 (METHOD_BUFFERED)
access: 0x0 (FILE_ANY_ACCESS)

# convert parts (<DeviceType> <Function> <Method> <Access>) given as ints into ioctl code.
$ CtlCode.exe 0x10 3 0 2
deviceType: 0x10 (FILE_DEVICE_MULTI_UNC_PROVIDER)
function: 0x3
method: 0x0 (METHOD_BUFFERED)
access: 0x2 (FILE_WRITE_DATA)

ioctl: 0x10800c

# convert parts (<DeviceType> <Function> <Method> <Access>) given as strings into ioctl code.
$ CtlCode.exe FILE_DEVICE_UCM 1 METHOD_NEITHER FILE_READ_DATA^|FILE_WRITE_ACCESS
deviceType: 0x57 (FILE_DEVICE_UCM)
function: 0x1
method: 0x3 (METHOD_NEITHER)
access: 0x3 (FILE_READ_DATA | FILE_WRITE_DATA)

ioctl: 0x57c007

Num2Bin

A (decimal or hex) number to binary converter. Converts a given number into binary format or a binary string to hex and decimal number. Highlights selected bits.

version

1.0.4
Last changed: 22.04.2024

build

$devcmd> build /n2b

options

• -n: Input number to convert to binary.
• -x: Input hex number to convert to binary. No prefix needed.
• -b: Input binary string to convert to a hex and decimal number.
• -m: Highlight bits at given offsets. Offsets begin with 0 from right to left. Separate with comma (1,3,4), give ranges with colon (4:7,12:15).
• -w: Width of displayed bits. Valid values are multiples of 8 <= 64. Default: 32.
• -s: Size of bit blocks. Valid values are powers of 2 <= 64. Default: 4.

-w, -s and -m only take effect if input is from -n or -x.

examples

$ Num2Bin.exe -n 13 // convert 13 to binary format 
$ Num2Bin.exe -n 0xd -w 8 -s 2 // convert 13 to binary format just showing 8 bits in 2 bit sized blocks
$ Num2Bin.exe -x d -m 0,2:4,8:16 // convert 13 to binary, highlighting bit 0, 2 to 4 and 8 to 16
$ Num2Bin.exe -b 11001101 // convert 11001101 to hex and dec
$ Num2Bin.exe -b "1100 1101" -m 7:4 // convert 11001101 to hex and dec and highlight bits 4 to 7

NtStatus2DosError

Convert an nt status code into a dos error code.

version

1.0.0
Last changed: 21.04.2023

build

$devcmd> build /s2dE

examples

$ NtStatus2DosError 0xC0000005

String2Hex

Convert strings into hex or hex into string.

version

1.0.0
Last changed: 21.04.2023

build

$devcmd> build /s2h

Options

• -a Convert ascii string into hex.
• -u Convert unicode (utf-16) string into hex.
• -na Convert hex byte string into ascii string/chars. If preceded with '0x', it will be interpreted as an uint64 (i.e. mostly as little endian).
• -nu Convert hex byte string into unicode (utf-16) string/chars. If preceded with '0x', it will be interpreted as an uint64 (i.e. mostly as little endian).
• -f Number format of output. Used with the -a or -u option. 1: bytes, 2: uint16, 4: uint32, 8: uint64

examples

$ String2hex -a bla // ascii string to hex uint8 => 62 6c 61
$ String2hex -a blub -f 2 // ascii string to hex uint16 => 6c62 6275
$ String2hex -u blob -f 4 // utf-16 string to hex uint32 => 006c0062 0062007f
$ String2hex -na 414243 // hex byte string into ascii => string: ABC, chars: A B C
$ String2hex -na 0x434241 // uint into ascii => string: ABC, chars: A B C (on little endian machines)
$ String2hex -nu 42006c006100 // hex byte string unicode => string: Bla, chars: B l a 
$ String2hex -nu 0x0061006c0042 // uint into unicode => string: Bla, wchars: B l a  (on little endian machines)
