CL_INVALID_DEVICE_TYPE	The passed-in device type is not a valid value.
CL_INVALID_PLATFORM	The passed-in platform is not a valid value
CL_INVALID_DEVICE	The passed-in device is not a valid value
CL_INVALID_CONTEXT	The passed-in context is not a valid value
CL_INVALID_QUEUE_PROPERTIES	The device does not support command-queue properties.
CL_INVALID_COMMAND_QUEUE	The passed-in command-queue is not a valid value.
CL_INVALID_HOST_PTR	The host pointer is not valid
CL_INVALID_MEM_OBJECT	The passed-in memory object is not a valid value.
CL_INVALID_IMAGE_FORMAT_DESCRIPTOR	The passed-in image format descriptor is not valid.
CL_INVALID_IMAGE_SIZE	The device does not support the image dimensions.
CL_INVALID_SAMPLER	The passed-in sampler is not a valid value.
CL_INVALID_BINARY	An invalid program binary was passed in.
CL_INVALID_BUILD_OPTIONS	One or more build options are not valid.
CL_INVALID_PROGRAM	The passed-in program is not a valid value.
CL_INVALID_PROGRAM_EXECUTABLE	The program was not successfully built into an executable for the devices associated with the command-queue
CL_INVALID_KERNEL_NAME	The named kernel does not exist in the program.
CL_INVALID_KERNEL_DEFINITION	The kernel defined in the program source is not valid.
CL_INVALID_KERNEL	The passed-in kernel is not a valid value
CL_INVALID_ARG_INDEX	The argument referred to by the argument index is not valid for the kernel
CL_INVALID_ARG_VALUE	The kernel argument value is NULL for a nonlocal argument or non-NULL for a local argument.
CL_INVALID_ARG_SIZE	The argument size does not match the kernel argument.
CL_INVALID_KERNEL_ARGS	One or more kernel arguments have not been assigned values.
CL_INVALID_WORK_DIMENSION	The value of the work dimension is not a value between 1 and 3.
CL_INVALID_WORK_GROUP_SIZE	The local or global work size is not valid
CL_INVALID_WORK_ITEM_SIZE	One or more work-item sizes exceed the maximum size supported by the device.
CL_INVALID_GLOBAL_OFFSET	The global offset exceeds supported bounds.
CL_INVALID_EVENT_WAIT_LIST	The wait list provided is either an invalid size or contains nonevents in it.
CL_INVALID_EVENT	The passed-in event is not a valid value
CL_INVALID_OPERATION	Executing the command caused an invalid operation to occur.
CL_INVALID_GL_OBJECT	There was a problem with the OpenGL-referenced object
CL_INVALID_BUFFER_SIZE	The buffer size specified was out of bounds.
CL_INVALID_MIP_LEVEL	The mipmap level specified for an OpenGL texture is not valid for the OpenGL object.
CL_INVALID_GLOBAL_WORK_SIZE	The global work size passed in is not valid because it is either 0 or exceeds the dimen-sions supported by the device
