C Specification

Alternatively, if you are not using OpenCL via the ICD loader, you may unload the OpenCL compiler with the function

cl_int clUnloadCompiler(


This function allows the implementation to release the resources allocated by the OpenCL compiler. This is a hint from the application and does not guarantee that the compiler will not be used in the future or that the compiler will actually be unloaded by the implementation. Calls to clBuildProgram, clCompileProgram or clLinkProgram after clUnloadCompiler will reload the compiler, if necessary, to build the appropriate program executable.


clUnloadCompiler will always return CL_​SUCCESS.
