DerelictAL

DerelictAL is a D binding to OpenAL, a cross-platform 3D audio API.

The current version of DerelictAL requires OpenAL 1.1 or later.

Building

To compile DerelictAL, add the DerelictAL make target to the command line when compiling Derelict. For example, to build DerelictAL on Windows with DMD, you would execute the following: 

make -fwin32.mak DerelictAL DC=DMD
For more information on compiling Derelict libraries, see Building the Derelict Bindings.

Using

  1. Always make sure the DerelictAL source modules are available on your import path.
  2. In modules that make use of DerelictAL, you will need to import the derelict.openal.al module.
  3. You must link your application with the DerelictAL and DerelictUtil libraries.
  4. Before calling any OpenAL functions, you need to make a call to DerelictAL.load. This will load the shared library.

The following is a complete program that loads DerelictAL: 


import derelict.openal.al;

void main()
{
    DerelictAL.load();

    // now you can call OpenAL functions
}

As with other Derelict bindings, DerelictAL will throw an exception if an error occurs while loading the shared library. For more information on Derelict exceptions, see the documentation for Using the Derelict Bindings.

Finally, the method DerelictAL.unload() is provided for convenience. In normal practice you do not need to call this function, as Derelict will unload the library automatically when the app exits. You generally should only use this function if you need to unload DerelictAL while the application is running or if you disable the automatic unloading of shared libraries (as per the documentation for the loader module).
