Module EndianBigstring.NativeEndian_unsafe

Contents

Instructions: Use this module in your project

In the IDE (CLion, Visual Studio Code, Xcode, etc.) you use for your DkSDK project:

  1. Add the following to your project's dependencies/CMakeLists.txt:

    Copy
    DkSDKProject_DeclareAvailable(ocplib-endian
        CONSTRAINT "= "
        FINDLIBS ocplib-endian ocplib-endian.bigstring)
    DkSDKProject_MakeAvailable(ocplib-endian)
  2. Add the Findlib::ocplib-endian library to any desired targets in src/*/CMakeLists.txt:

    Copy
    target_link_libraries(YourPackage_YourLibraryName
         # ... existing libraries, if any ...
         Findlib::ocplib-endian)
  3. Click your IDE's Build button

Not using DkSDK?

FIRST, do one or all of the following:

  1. Run:

    Copy
    opam install ocplib-endian.null
  2. Edit your dune-project and add:

    Copy
    (package
      (name YourExistingPackage)
      (depends
      ; ... existing dependenices ...
      (ocplib-endian (>= ))))

    Then run:

    Copy
    dune build *.opam # if this fails, run: dune build
  3. Edit your <package>.opam file and add:

    Copy
    depends: [
      # ... existing dependencies ...
      "ocplib-endian" {>= ""}
    ]

    Then run:

    Copy
    opam install . --deps-only

FINALLY, add the ocplib-endian.bigstring library to any desired (library)and/or (executable) targets in your **/dune files:

Copy
(library
  (name YourLibrary)
  ; ... existing library options ...
  (libraries
    ; ... existing libraries ...
    ocplib-endian.bigstring))

(executable
  (name YourExecutable)
  ; ... existing executable options ...
  (libraries
    ; ... existing libraries ...
    ocplib-endian.bigstring))

valget_char :bigstring ->``int-> char

get_char buff i reads 1 byte at offset i as a char

valget_uint8 :bigstring ->``int-> int

get_uint8 buff i reads 1 byte at offset i as an unsigned int of 8 bits. i.e. It returns a value between 0 and 2^8-1

valget_int8 :bigstring ->``int-> int

get_int8 buff i reads 1 byte at offset i as a signed int of 8 bits. i.e. It returns a value between -2^7 and 2^7-1

valget_uint16 :bigstring ->``int-> int

get_uint16 buff i reads 2 bytes at offset i as an unsigned int of 16 bits. i.e. It returns a value between 0 and 2^16-1

valget_int16 :bigstring ->``int-> int

get_int16 buff i reads 2 byte at offset i as a signed int of 16 bits. i.e. It returns a value between -2^15 and 2^15-1

valget_int32 :bigstring ->``int-> int32

get_int32 buff i reads 4 bytes at offset i as an int32.

valget_int64 :bigstring ->``int-> int64

get_int64 buff i reads 8 bytes at offset i as an int64.

valget_float :bigstring ->``int-> float

get_float buff i is equivalent to Int32.float_of_bits (get_int32 buff i)

valget_double :bigstring ->``int-> float

get_double buff i is equivalent to Int64.float_of_bits (get_int64 buff i)

valset_char :bigstring ->``int->``char-> unit

set_char buff i v writes v to buff at offset i

valset_int8 :bigstring ->``int->``int-> unit

set_int8 buff i v writes the least significant 8 bits of v to buff at offset i

valset_int16 :bigstring ->``int->``int-> unit

set_int16 buff i v writes the least significant 16 bits of v to buff at offset i

valset_int32 :bigstring ->``int->``int32-> unit

set_int32 buff i v writes v to buff at offset i

valset_int64 :bigstring ->``int->``int64-> unit

set_int64 buff i v writes v to buff at offset i

valset_float :bigstring ->``int->``float-> unit

set_float buff i v is equivalent to set_int32 buff i (Int32.bits_of_float v)

valset_double :bigstring ->``int->``float-> unit

set_double buff i v is equivalent to set_int64 buff i (Int64.bits_of_float v)
