Any equivalent to strerror() for OpenCL?

I searched through the 1.1 spec and the C++ interface, and I'm not seeing any function that translates error codes into strings (similar to strerror()).  Am I missing it, or is such a thing not provided?

Re: Any equivalent to strerror() for OpenCL?

Here's something simple I whipped up:

const char *StrClError( cl_int i )
{
#define CASE( val ) case val: return #val;

    switch (i)
    {
        CASE( CL_SUCCESS )
        CASE( CL_DEVICE_NOT_FOUND )
        CASE( CL_DEVICE_NOT_AVAILABLE )
        CASE( CL_COMPILER_NOT_AVAILABLE )
        CASE( CL_MEM_OBJECT_ALLOCATION_FAILURE )
        CASE( CL_OUT_OF_RESOURCES )
        CASE( CL_OUT_OF_HOST_MEMORY )
        CASE( CL_PROFILING_INFO_NOT_AVAILABLE )
        CASE( CL_MEM_COPY_OVERLAP )
        CASE( CL_IMAGE_FORMAT_MISMATCH )
        CASE( CL_IMAGE_FORMAT_NOT_SUPPORTED )
        CASE( CL_BUILD_PROGRAM_FAILURE )
        CASE( CL_MAP_FAILURE )
        CASE( CL_MISALIGNED_SUB_BUFFER_OFFSET )
        CASE( CL_EXEC_STATUS_ERROR_FOR_EVENTS_IN_WAIT_LIST )
        CASE( CL_INVALID_VALUE )
        CASE( CL_INVALID_DEVICE_TYPE )
        CASE( CL_INVALID_PLATFORM )
        CASE( CL_INVALID_DEVICE )
        CASE( CL_INVALID_CONTEXT )
        CASE( CL_INVALID_QUEUE_PROPERTIES )
        CASE( CL_INVALID_COMMAND_QUEUE )
        CASE( CL_INVALID_HOST_PTR )
        CASE( CL_INVALID_MEM_OBJECT )
        CASE( CL_INVALID_IMAGE_FORMAT_DESCRIPTOR )

        CASE( CL_INVALID_ARG_VALUE )
        CASE( CL_INVALID_ARG_SIZE )
        CASE( CL_INVALID_KERNEL_ARGS )
        CASE( CL_INVALID_WORK_DIMENSION )
        CASE( CL_INVALID_WORK_GROUP_SIZE )
        CASE( CL_INVALID_WORK_ITEM_SIZE )
        CASE( CL_INVALID_GLOBAL_OFFSET )
        CASE( CL_INVALID_EVENT_WAIT_LIST )
        CASE( CL_INVALID_EVENT )
        CASE( CL_INVALID_OPERATION )
        CASE( CL_INVALID_GL_OBJECT )
        CASE( CL_INVALID_BUFFER_SIZE )
        CASE( CL_INVALID_MIP_LEVEL )
        CASE( CL_INVALID_GLOBAL_WORK_SIZE )
        CASE( CL_INVALID_PROPERTY )
    }

#undef CASE

    return "Unknown or invalid error code";
}

Re: Any equivalent to strerror() for OpenCL?

But if anyone know of anything better or bulit-in, please speak up.

The fewer util functions I have to cart around, the better.
