Module Random.State

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(ocaml
        CONSTRAINT "= 4.14.0"
        FINDLIBS str unix runtime_events threads dynlink)
    DkSDKProject_MakeAvailable(ocaml)
  2. Add the Findlib::ocaml library to any desired targets in src/*/CMakeLists.txt:

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

Not using DkSDK?

FIRST, do one or all of the following:

  1. Run:

    Copy
    opam install ocaml.4.14.0
  2. Edit your dune-project and add:

    Copy
    (package
      (name YourExistingPackage)
      (depends
      ; ... existing dependenices ...
      (ocaml (>= 4.14.0))))

    Then run:

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

    Copy
    depends: [
      # ... existing dependencies ...
      "ocaml" {>= "4.14.0"}
    ]

    Then run:

    Copy
    opam install . --deps-only

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

Copy
(library
  (name YourLibrary)
  ; ... existing library options ...
  (libraries
    ; ... existing libraries ...
    ))

(executable
  (name YourExecutable)
  ; ... existing executable options ...
  (libraries
    ; ... existing libraries ...
    ))
type t

The type of PRNG states.

valmake : ``int array``-> t

Create a new state and initialize it with the given seed.

valmake_self_init : ``unit-> t

Create a new state and initialize it with a system-dependent low-entropy seed.

valcopy :t -> t

Return a copy of the given state.

valbits :t -> int
valint :t ->``int-> int
valfull_int :t ->``int-> int
valint32 :t -> Int32.t -> Int32.t
valnativeint :t -> Nativeint.t -> Nativeint.t
valint64 :t -> Int64.t -> Int64.t
valfloat :t ->``float-> float
valbool :t -> bool
valbits32 :t -> Int32.t
valbits64 :t -> Int64.t
valnativebits :t -> Nativeint.t

These functions are the same as the basic functions, except that they use (and update) the given PRNG state instead of the default one.
