public interface BuildProgramCallbackA callback an application can register to be called when the program executable has been built (successfully or unsuccessfully).
Note1: registering a build callback can make
CL.clBuildProgram(long, int, com.jogamp.common.nio.PointerBuffer, java.lang.String, com.jogamp.opencl.llb.impl.BuildProgramCallback)non blocking (OpenCL implementation dependent).
Note2: the thread which calls this method is unspecified. The Application should ensure proper synchronization.
