<!-- ================================ PARAMETERS -->
<refsect1 id="parameters">
<term><varname>source_kernel</varname> </term>
<para><!-- this corrects a probable typo in the 2.1 spec, replace "with not" with "will not" -->
A valid <type>cl_kernel</type> object that will be copied.
<varname>source_kernel</varname> will not be
modified in any way by this function.
<term> <varname>errcode_ret</varname> </term>
Assigned an appropriate error code. If <varname>errcode_ret</varname>
is <code>NULL</code>, no error code is returned.
<!-- ================================ DESCRIPTION -->
<refsect1 id="description"><title>Description</title>
Makes a shallow copy of the kernel object,
its arguments and any information passed to
the kernel object using
If the kernel object was ready to be enqueued
before copying it, the clone of the kernel
object is ready to enqueue.
<!-- ================================ NOTES -->
<refsect1 id="notes"><title>Notes</title>
The returned kernel object is an exact copy of
<varname>source_kernel</varname>, with one caveat: the reference
count on the returned kernel object is set as if it had been returned by
<citerefentry><refentrytitle>clCreateKernel</refentrytitle></citerefentry> .
The reference count of <varname>source_kernel</varname> will not be changed.
The resulting kernel will be in the same state as if
is called to create the
resultant kernel with the same arguments as those used to create
<varname>source_kernel</varname>, the latest call to
for each argument index applied to kernel and
the last call to
for each value of the param name parameter are applied to
the new kernel object.
All arguments of the new kernel object must be intact and it may be correctly used in the same
situations as kernel except those that assume a pre-existing reference count. Setting arguments on
the new kernel object will not affect <varname>source_kernel</varname> except insofar as the argument points to a
shared underlying entity and in that situation behavior is as if two kernel objects had been
created and the same argument applied to each. Only the data stored in the kernel object is
copied; data referenced by the kernel’s arguments are not copied. For example, if a buffer or
pointer argument is set on a kernel object, the pointer is copied but the underlying memory
allocation is not.
<!-- ================================ ERRORS -->
<refsect1 id="errors"><title>Errors</title>
Returns a valid non-zero kernel object and
<varname>errcode_ret</varname> is set to
<constant>CL_SUCCESS</constant> if
the kernel is successfully copied. Otherwise
it returns a NULL value with one of the following
error values returned in
<itemizedlist mark="disc">
<errorname>CL_INVALID_KERNEL</errorname> if
<varname>kernel</varname> is not a valid kernel object.
if there is a failure to allocate resources required by the
OpenCL implementation on the device.
if there is a failure to allocate resources required by the
OpenCL implementation on the host

Example goes here - it will be set in "code" type with white space preserved.
