| <!-- ================================ NOTES --> |
| <refsect1 id="notes"><title>Notes</title> |
| <para> |
| As specified for <citerefentry><refentrytitle>clCreateCommandQueue</refentrytitle></citerefentry>, the <constant>CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE</constant> command-queue property determines whether the commands in a command-queue are executed in-order or out-of-order. Changing this command-queue property will cause the OpenCL implementation to block until all previously queued commands in <varname>command_queue</varname> have completed. This can be an expensive operation and therefore changes to the <constant>CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE</constant> property should be only done when absolutely necessary. |
| </para> |
| <para> |
| It is possible that a device(s) becomes unavailable after a context and command-queues that use this device(s) have been created and commands have been queued to command-queues. In this |
| case the behavior of OpenCL API calls that use this context (and command-queues) are |
| considered to be implementation-defined. The user callback function, if specified when the |
| context is created, can be used to record appropriate information in the <varname>errinfo</varname>, <varname>private_info</varname> arguments passed to the callback function when the device becomes unavailable. |

| <para>Returns <errorname>CL_SUCCESS</errorname> if the command-queue properties are successfully updated. Otherwise, it returns the following:</para> |
| <itemizedlist mark="disc"> |
| <listitem> |
| Returns <errorname>CL_INVALID_COMMAND_QUEUE</errorname> if <varname>command_queue</varname> is not a valid command-queue. |

| <listitem> |
| Returns <errorname>CL_INVALID_VALUE</errorname> if the values specified in <varname>properties</varname> are not valid. |
