<div class="sectionbody">
<div class="paragraph">
<p>Kernel objects are not created for any <code>__kernel</code> functions in <em>program</em>
that do not have the same function definition across all devices for which a
program executable has been successfully built.</p>
</div>
<div class="paragraph">
<p>Kernel objects can only be created once you have a program object with a
valid program source or binary loaded into the program object and the
program executable has been successfully built for one or more devices
associated with program.
No changes to the program executable are allowed while there are kernel
objects associated with a program object.
This means that calls to <strong>clBuildProgram</strong> and <strong>clCompileProgram</strong> return
CL_INVALID_OPERATION if there are kernel objects attached to a program
object.
The OpenCL context associated with <em>program</em> will be the context associated
with <em>kernel</em>.
The list of devices associated with <em>program</em> are the devices associated
with <em>kernel</em>.
Devices associated with a program object for which a valid program
executable has been built can be used to execute kernels declared in the
program object.</p>
</div>
<div class="paragraph">
<p><strong>clCreateKernelsInProgram</strong> will return CL_SUCCESS if the kernel objects were
successfully allocated.
Otherwise, it returns one of the following errors:</p>
</div>
<div class="ulist">
<ul>
<li>
<p>CL_INVALID_PROGRAM if <em>program</em> is not a valid program object.</p>
</li>
<li>
<p>CL_INVALID_PROGRAM_EXECUTABLE if there is no successfully built
executable for any device in <em>program</em>.</p>
</li>
<li>
<p>CL_INVALID_VALUE if <em>kernels</em> is not <code>NULL</code> and <em>num_kernels</em> is less
than the number of kernels in <em>program</em>.</p>
</li>
<li>
<p>CL_OUT_OF_RESOURCES if there is a failure to allocate resources required
by the OpenCL implementation on the device.</p>
</li>
<li>
<p>CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources
required by the OpenCL implementation on the host.</p>
