<!-- ================================ SYNOPSIS -->
<refnamediv id="clWaitForEvents">
Waits on the host thread for commands identified by event objects to complete.
<refsynopsisdiv xmlns:xlink=""><title></title>
<link xlink:href="scalarDataTypes.html">cl_int</link>
<paramdef><link xlink:href="scalarDataTypes.html">cl_uint</link><parameter>num_events</parameter></paramdef>
<paramdef>const <link xlink:href="abstractDataTypes.html">cl_event</link><parameter>*event_list</parameter></paramdef>
<!-- ================================ PARAMETERS -->
<refsect1 id="parameters"><title>Parameters</title>
The events specified in <varname>event_list</varname> act as synchronization points.
<!-- ================================ NOTES -->
<refsect1 id="notes"><title>Notes</title>
Waits on the host thread for commands identified by event objects in <varname>event_list</varname> to
complete. A command is considered complete if its execution status is <constant>CL_COMPLETE</constant>
or a negative value.
If the <citerefentry href="gl_event"><refentrytitle>cl_khr_gl_event</refentrytitle></citerefentry> extension
is enabled, event objects can also be used to reflect the status of an OpenGL sync object. The sync object
in turn refers to a fence command executing in an OpenGL command stream. This provides another method of
coordinating sharing of buffers and images between OpenGL and OpenCL.
<!-- ================================ ERRORS -->
<refsect1 id="errors"><title>Errors</title>
Returns <errorname>CL_SUCCESS</errorname> if the execution status of all
events in <varname>event_list</varname> is CL_COMPLETE.
Otherwise, it returns one of the following errors:
<itemizedlist mark="disc">
<errorname>CL_INVALID_VALUE</errorname> if <varname>num_events</varname> is zero or <varname>event_list</varname> is NULL..
<errorname>CL_INVALID_CONTEXT</errorname> if events specified in <varname>event_list</varname> do
not belong to the same context.
<errorname>CL_INVALID_EVENT</errorname> if event objects specified in <varname>event_list</varname>
are not valid event objects.
<errorname>CL_EXEC_STATUS_ERROR_FOR_EVENTS_IN_WAIT_LIST</errorname> if the execution status
of any of the events in <varname>event_list</varname> is a negative integer value.
<errorname>CL_OUT_OF_RESOURCES</errorname> if there is a failure to allocate resources required by the
OpenCL implementation on the device.
<errorname>CL_OUT_OF_HOST_MEMORY</errorname> if there is a failure to allocate resources required
by the OpenCL implementation on the host.
<!-- ================================ EXAMPLE -->
<refsect2 id="example1">

<colspec colname="col1" colnum="1" />
Example goes here - it will be set in "code" type with white space preserved.
