NAME

       clCreateKernel - Creates a kernel object.

       cl_kernel clCreateKernel(cl_program program, const char *kernel_name,
                                cl_int *errcode_ret);

PARAMETERS

        program
           A program object with a successfully built executable.

        kernel_name
           A function name in the program declared with the __kernel qualifier

        errcode_ret
           Returns an appropriate error code. If errcode_ret is NULL, no error code is returned.

NOTES

       A kernel is a function declared in a program. A kernel is identified by the
       functionQualifiers(3clc) qualifier applied to any function in a program. A kernel object
       encapsulates the specific __kernel function declared in a program and the argument values
       to be used when executing this __kernel function.

ERRORS

       clCreateKernel returns a valid non-zero kernel object and errcode_ret is set to CL_SUCCESS
       if the kernel object is created successfully. Otherwise, it returns a NULL value with one
       of the following error values returned in errcode_ret:

       •   CL_INVALID_PROGRAM if program is not a valid program object.

       •   CL_INVALID_PROGRAM_EXECUTABLE if there is no successfully built executable for
           program.

       •   CL_INVALID_KERNEL_NAME if kernel_name is not found in program.

       •   CL_INVALID_KERNEL_DEFINITION if the function definition for __kernel function given by
           kernel_name such as the number of arguments, the argument types are not the same for
           all devices for which the program executable has been built.

       •   CL_INVALID_VALUE if kernel_name is NULL.

       •   CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL
           implementation on the device.

       •   CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the
           OpenCL implementation on the host.
