C Specification

To unload an OpenCL compiler for a platform, call the function

cl_int clUnloadPlatformCompiler(
    cl_platform_id platform);


  • platform is the platform to unload.


This function allows the implementation to release the resources allocated by the OpenCL compiler for platform. 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 clUnloadPlatformCompiler will reload the compiler, if necessary, to build the appropriate program executable.

clUnloadPlatformCompiler returns CL_​SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors:

  • CL_​INVALID_​PLATFORM if platform is not a valid platform.
