Instructions: Use this module in your project
In the IDE (CLion, Visual Studio Code, Xcode, etc.) you use for your DkSDK project:
Add the following to your project's
dependencies/CMakeLists.txt
:DkSDKProject_DeclareAvailable(ocaml CONSTRAINT "= 4.14.0" FINDLIBS str unix runtime_events threads dynlink) DkSDKProject_MakeAvailable(ocaml)
Add the
Findlib::ocaml
library to any desired targets insrc/*/CMakeLists.txt
:target_link_libraries(YourPackage_YourLibraryName # ... existing libraries, if any ... Findlib::ocaml)
Click your IDE's
Build
button
Not using DkSDK?
FIRST, do one or all of the following:
Run:
opam install ocaml.4.14.0
Edit your
dune-project
and add:(package (name YourExistingPackage) (depends ; ... existing dependenices ... (ocaml (>= 4.14.0))))
Then run:
dune build *.opam # if this fails, run: dune build
Edit your
<package>.opam
file and add:depends: [ # ... existing dependencies ... "ocaml" {>= "4.14.0"} ]
Then run:
opam install . --deps-only
FINALLY, add the unix threads
library to any desired (library)
and/or (executable)
targets in your **/dune
files:
(library
(name YourLibrary)
; ... existing library options ...
(libraries
; ... existing libraries ...
unix threads))
(executable
(name YourExecutable)
; ... existing executable options ...
(libraries
; ... existing libraries ...
unix threads))
type
t
The type of condition variables.
val
create : ``unit
->
t
Return a new condition variable.
wait c m
atomically unlocks the mutex m
and suspends the calling
process on the condition variable c
. The process will restart after
the condition variable c
has been signalled. The mutex m
is locked
again before wait
returns.
val
signal :
t
->
unit
signal c
restarts one of the processes waiting on the condition
variable c
.
val
broadcast :
t
->
unit
broadcast c
restarts all processes waiting on the condition variable
c
.
