<para>
Returns a list of OpenCL platforms available for access through the
Khronos ICD Loader. The <type>cl_platform_id</type> values returned in
<varname>platforms</varname> are ICD compatible and can be used to
identify a specific OpenCL platform. If the <varname>platforms</varname>
argument is NULL, then this argument is ignored. The number of
OpenCL platforms returned is the minimum of the value specified by
<varname>num_entries</varname> or the number of OpenCL platforms available.
